Monday's Weather Thoughts

Memorial Day Weekend was not really too bad weather-wise in most areas for outdoor plans, but late-day storms Saturday and some clouds both Sunday morning and this morning likely either stopped or delayed some outdoor activities.

Looking into the rest of the workweek, it will be changeable and active. Tonight will be partly cloudy with the risk of an isolated thunderstorm with lows near 60. There is a better chance of storms later Tuesday and Tuesday night, some perhaps strong, as a front presses southward and through Greater Nebraska by Wednesday morning. Highs Tuesday will be in the lower 80’s under partly sunny skies.

The front will stall just to our south during Wednesday, which could start with some morning showers but will turn partly sunny with highs in the 70’s. The front will begin to move back northward as a warm front on Thursday, and as it does, it will tap into some very hot air over the southern Plains, where highs will be in the 100 degree range as close to our region as the panhandle of Texas. While air that hot will not reach this area, temperatures will begin to climb again Thursday, getting into the 80’s, and Friday could be very warm, with highs near or topping 90.

Right now, the weekend is looking nice after some morning storms on Saturday, and Sunday is looking mainly sunny and nice with highs near 80.

Memorial Day Weekend – Is It Already Summer?

Memorial Day Weekend is often referred to as the "unofficial" start to the Summer season. Of course, the Summer season “officially” begins June 21st at 6:28am CDT, when the sun is at its northernmost point in the Northern Hemisphere at the Tropic of Cancer. This date marks the summer solstice and is the date that most people think of when it comes to the start of summer. However, while this is true from an astronomical standpoint (known as “Astronomical Summer”), it could be argued that the summer season began weeks ago, and even as early as the first week in May! Now before you think I have gone completely crazy (I may be slightly so but not completely so just yet), let me explain.

There are at least two other beginnings to the “Summer” season that you may or may not have heard about before. The first is what is known as “Meteorological Summer”, and its start date varies a bit from place to place due to latitude, elevation, and proximity to large bodies of water. Meteorological Summer encompasses the warmest 90 days of the year, and it typically begins sometime in the first or second week of June, and ends during the first or second week of September. Sometimes the period used is simply the months of June, July and August. Meteorologists and Climatologists often refer to this period when discussing the summer season in general.

Another ‘beginning’ to the Summer season is called “Solar Summer”, and it encompasses the 90-day period of the year that the amount of solar radiation is at its maximum. In the Northern Hemisphere, this occurs during the period from the first week in May to the first week in August, with the first day of Astronomical Summer as its midpoint. Note that Solar Summer begins about one month before Meteorological Summer, and this occurs because it takes a bit of time to warm the earth, even when the amount of solar energy available to do so is at its peak.

Looks like determining the beginning of summer is a bit more complicated than we thought, right:-)

Friday's Weather Thoughts

Memorial Day Weekend is here! But thunderstorms, possibly severe, will likely affect much of Greater Nebraska Saturday evening and night.

Tonight will be clear and breezy but mild with lows in the middle 60’s, so a pleasant night to be outside.

Saturday will be mainly sunny much of the day and breezy with highs once again approaching 90. However, a cold front approaching from the west will spark thunderstorms towards evening, maybe late afternoon over western and northern areas. These storms could turn severe, and while isolated tornadoes are possible, the main threats will be large hail, damaging winds, and heavy rainfall. In fact, eastern Cherry County is under a Flash Flood Watch as thunderstorms there will be capable of dumping very heavy rain in a short amount of time as the front begins to slow a bit and some upper-level energy has a greater affect in northern areas.

The storms will continue into the night, and perhaps well into the overnight across southern and eastern areas. By sunrise Sunday, the cold front should be far enough to the east that storms will have ended, and Sunday and Monday are looking sunny to partly sunny and pleasant with highs anywhere from the upper 60’s to upper 70’s. Sunday may still be a bit breezy.

Stay tuned to News 2 for the latest on Saturday’s severe storm threat. Enjoy and be safe this holiday weekend!

Thursday's Weather Thoughts

Today was mostly sunny and warm, but some areas had a thunderstorm this morning that dropped very heavy rain on the order of 2 to 3 inches in a short period of time. It was also breezy today, and those winds will increase a bit and stay with us through Saturday.

Tonight will be partly cloudy and mild with the wind diminishing just a bit but it will still be breezy with lows in the middle 60’s.
Friday will be sunny and very warm to hot with high around 90, but winds gusting to 35mph will make it a bit difficult outside.

The start of the long holiday weekend on Saturday will feature highs around 90 once again, but this time with the chance of thunderstorms during the afternoon as a front approaches. Some of these storms may turn severe, and it will still be breezy to windy.

However, by Sunday the front will have moved through and fair, breezy and cooler conditions will set in with high in the 70’s, and this fair weather will continue for Memorial Day as well.

Stay tuned to News 2 for updates on your holiday weekend weather.

Wednesday's Weather Thoughts

After some early morning thunderstorms over extreme southwest parts of our viewing area, i.e., Imperial and Ogallala, today turned very nice with sunshine and highs in the upper 70’s with a light breeze.

A warm front will move through the area overnight and into Thursday, and this will set off a few isolated thunderstorms with the greatest chance over southwestern and western Nebraska, similar to the area that reported storms this morning. It is not out of the question that on or two of the storms turns strong, with some hail and high wind gusts, but any severe weather for the most part should stay to the west of Greater Nebraska over the western Panhandle, and into eastern Wyoming and Colorado where a Tornado Watch is in effect until 9PM MDT. Lows will be in the upper 50’s.

Once the warm front moves through, Thursday will turn quite breezy to windy as southerly winds gust to 35mph and locally higher, but sunshine will boost highs into the middle 80’s. Similar weather is expected for Friday but breezy to windy conditions, sunshine and highs a few degrees warmer.

The next chance of any severe weather will come at the start of the long holiday weekend on Saturday, as a potent system passes by to our north and west and drags a cold front through the region during Saturday. The setup will be somewhat similar to what occurred Sunday night and Monday, and it is possible that strong, gusty winds may occur again during Saturday, along with a chance of strong to severe storms. Stay tuned to News 2 during the next few days for updates on this potential storm situation.

After the cold front passes, Sunday and Memorial Day Monday are looking fair and pleasant, with highs in the lower 70’s.

Mike

Tuesday, May 25, 2010

Tuesday's Weather Thoughts

We deserved a tranquil day of weather after the severe storms and wind of the last couple of days, and today certainly was tranquil and pleasant.

The system that caused all the weather problems yesterday has not gotten very far, with the front stalled out over eastern Nebraska southward into Kansas, then northward into Colorado. The front cannot go very far east because the upper flow is basically southwest parallel to the front, so it’s stalled but will begin to move back northward through Thursday as the upper flow continues out of the south. This front, along with an upper disturbance, will produce a few isolated showers and thunderstorms across the viewing area tonight and Wednesday, but most places won’t see any precipitation, and any storms are not expected to become severe. Lows tonight will be around 50, and highs tomorrow will get into the upper 70’s under partly cloudy skies.

Fair and warmer weather will return later in the week as the front moves to our north, allowing warmer and more humid air back into Greater Nebraska. The next chance of any precipitation will come later Saturday into Sunday morning as another system moves to our west, dragging a cold front through. We’ll have to watch not only the timing of this system, but also the possibility that it could produce some severe storms during a portion of the long holiday weekend.

At this point, Memorial Day Monday looks fair and cooler with highs in the lower 70’s.

Mike

Monday's Weather Thoughts - Severe Weather Wrap-up

The severe weather that has plagued the viewing area since last night, and the high winds that caused several reports of damage today, are now ending and the overnight and Tuesday will be much more tranquil.

Tonight will be partly cloudy and chilly late with lows in the 40's with much lighter winds. Tuesday will be sunny and pleasant in the afternoon with highs in the lower 70's.

The next chance of isolated thunderstorms will come very late Tuesday night into Wednesday as a disturbance moves northeast from New Mexico toward the area, but nothing severe is anticipated at this time.

Fair and warmer weather will end the week. The start of the holiday weekend is looking mainly fair but with a chance of thunderstorms at night on Saturday and into Sunday. Memorial Day should be fair and seasonable.

Mike

Friday, May 21, 2010

Friday's Weather Thoughts

Summer doesn’t officially arrive for another month, but it will feel very much like summer on Saturday!

Tonight will be partly cloudy and breezy with lows in the 50’s, and there may be an isolated strong thunderstorm as a front approaches from the west and stalls to our west, but most areas will not see one.

Saturday will again be breezy, but sunshine and a southerly breeze will bring in air that originated from over the desert southwest, so highs will soar well into the 80’s, and I wouldn’t be surprised if a few areas touched or exceeded 90. The stalled front will begin to push eastward slowly across Greater Nebraska during the afternoon, and this could set off a few strong to severe storms, but again most areas won’t see any activity so outdoor plans shouldn’t be greatly affected.

The front will have pushed through the viewing area by Sunday, so highs will be a bit cooler, topping out in the upper 70’s to lower 80’s, but with some sunshine it will still be very pleasant and still breezy. The front to our south will begin to push back northward later in the day, so a few thunderstorms may form but will be relatively isolated.

This front will remain in the vicinity through midweek, providing the risk of a few storms each day, but temperatures will remain above average with highs near 80.

Mike

Thursday, May 20, 2010

Thursday's Weather Thoughts

The beginning of the end of this weeks-long cool period will begin Friday.

The area of low pressure that has plagued our weather since Tuesday evening has now moved far enough east to begin losing its grip on Greater Nebraska. Skies tonight will turn partly cloudy, but fog will develop later and may become quite dense in spots so caution is advised if driving. Lows will fall into the 40’s.

Friday will start will fog, some of it dense, but the fog should burn off by late morning or early afternoon and skies will be mostly sunny with highs in the middle 70’s with breezy conditions developing. If the temperature gets to the predicted 74, it will be the first time since May 4th (when the high was 77) that the high was above average.

A front approaching the area Friday night will stall to the north and west of the viewing area, but could be close enough to set off an isolated thunderstorm over our western zones with lows in the 50’s.

The summer-like warmth will develop Saturday as a warm front pushes through, and ushers in air that originated over the southwest desert areas. Skies will be mainly sunny and it will be breezy, but highs will reach the middle 80’s to perhaps 90 in a few spots.

Sunday will be a bit cooler as a bit more in the way of clouds and a wind shift cause highs to rise to the upper 70’s to lower 80’s, still a warm day. In addition, an isolated thunderstorm could develop but it should not be enough to disrupt outdoor plans for the most part.

Thunderstorms will be possible early next week, but warm temperatures will continue.

Mike

Wednesday, May 19, 2010

Wednesday's Weather Thoughts

Much of Greater Nebraska received a soaking rain overnight and today, though thunderstorms that I thought would cause even heavier rainfall did not materialize.

Regardless, rain amounts from only one-tenth of an inch up to and over one and one-half inches fell, and the rain will continue overnight before tapering off during Thursday. There still could be an isolated storm tonight and Thursday, especially across eastern areas, but any storms should be few. Lows tonight will settle into the 40’s, and highs Thursday will approach 60. Some sun could even peek out during the afternoon tomorrow.

Friday will begin the transition to a more summerlike pattern, but highs are a tough call since fog, perhaps dense, is likely overnight Thursday into Friday morning. If this fog lingers into the afternoon, highs will be held down into the lower 70’s and perhaps even upper 60’s. However, is the fog is not as dense or burns off quickly, highs could reach the upper 70’s.

But the real warmth will come Saturday and Sunday as highs approach the middle 80's. Temperatures could even go higher since we will be tapping into some desert warmth, but a couple of weather systems will keep a threat of thunderstorms in the forecast from the weekend through early next week. Any storms would hold highs down a bit, but even if storms do develop it will not rain the entire time.

Check back with News 2 over the next couple of days to get updates on the weekend forecast.

Mike

Tuesday, May 18, 2010

Tuesday's Weather Thoughts

A rainy and stormy 36 hours is on tap for Greater Nebraska.

An area of low pressure developing over southeastern Colorado will move slowly east-southeastward over the next couple of days. A broad southeasterly flow of moisture from off of the Gulf of Mexico riding northward into Greater Nebraska will cause showers and thunderstorms to develop tonight, and become more numerous after midnight and then continue through the day tomorrow. Lows tonight will fall into the lower 50’s, and highs tomorrow will only reach the upper 50’s with breezy conditions.

Some of the storms especially later tonight through tomorrow morning could be strong to locally severe, and some heavy rainfall is likely which may produce localized flooding. Anywhere from one-half to two plus inches of rain is expected by the time the activity tapers off Thursday afternoon.

Friday is looking nice and pleasant with sunshine and highs in the middle 70’s. The weekend is still looking summerlike with sunshine and temperature into the lower to perhaps middle 80’s. However, new weather systems have the opportunity to produce more showers and storms, and some of these could be severe. However, the timing of these systems is still in question so please stay tuned to News 2 for updates through the week. Also, check back for updates on the current storm situation.

Mike

Monday, May 17, 2010

Monday's Weather Thoughts

The weather will be quite active once again this week, especially for the middle of the week.

After the dense morning fog burned off, the afternoon turned much nicer with sunshine and highs near 70. Tonight will be fair, with clear skies early then some clouds overnight with lows in the 40’s.

Tuesday will start partly sunny in the morning, but clouds will increase during the afternoon, and by late afternoon we cloud see a thunderstorm with highs in the 60’s.
The real action will begin tomorrow night and last through the day on Wednesday as a developing area of low pressure over Colorado will introduce the likelihood of showers and thunderstorms, and while no widespread severe weather is anticipated at this time, some of the storms could be strong and also cause some heavy rainfall. In fact, most areas in Greater Nebraska should see anywhere from one half to as much as one inch or more of rain by the time the system exits to the east during Thursday.

Then some summerlike weather is possible as highs will finally reach the 70’s on Friday, and it’s quite possible that highs in the 80’s occur over the weekend. Also, another system will bring the change of showers and thunderstorms later in the weekend, although Saturday looks mainly dry right now.

Stay tuned to News 2 for the latest on our midweek storms.

Tornado Season 2010 - Active Or Not For Nebraska

So far, tornado season in Nebraska has been well below average. Up to May 14th, there have been only three tornado reports and on average, we should have seen about 10 tornadoes. By the end of May, we would typically have seen about 16 tornadoes.

Using tornado data from UNL for the period 1950 to 2006 (a great site by the way), I came up with some probabilities for the chances of a below or above average June and season as a whole based on the activity of the first three months of tornado season - March, April and May.

Looking at the numbers on the graphic, if the early part of tornado season, i.e., the first 3 months, is below average tornado-wise for Nebraska, then chances are very good that June and the entire season end up being below average. However, if the early season is average or above, the chances are 50-50 that June will be active, but very good that the season as a whole will be active.

The reason for this may lie in the fact that certain weather patterns tend to become established during a season, and many times early on in a season, so that once a pattern is in place it often continues. Take this year's snow season for example - heavy snow started very early in October, and while every month was not snowy the general trend for the winter was that of above average snowfall. The same can happen in the summer, and a hot June can be a sign that the rest of the summer season will be quite hot. But there are exceptions, and the graphic certainly shows that not all active or inactive early seasons produce the same results.

The good news is that no severe weather is foreseen for the next several days, so our quiet severe season continues for now. Let's hope that it continues indefinitely.

Mike


Friday's Weather Thoughts

An unsettled weekend is in store for Greater Nebraska, especially Saturday.

High pressure over Iowa and an upper-level low over Utah are working together to cause a southerly flow of moisture, and clouds are already beginning to increase across the viewing area. Showers and thunderstorms are prevalent over Texas northwestward into Colorado, where a trough is even causing some mountain snow. Eventually some of this southern moisture will cause showers to develop over our area, beginning after midnight then continuing through Saturday. A thunderstorm is also possible, and highs will hold in the 50’s due to abundant cloud cover.

The showers will continue into Saturday night, but as the upper low moves into Nebraska on Sunday, showers and thunderstorms will become more isolated and we should see more in the way of sunshine, so highs will get into the 60’s once again.

After a fair and pleasant Monday, active weather will return for the middle of next week with near seasonable temperatures. No return to the very cool temperatures of this past week are foreseen, and chances are good that frost and freezes are over until sometime next fall.

Mike

Thursday, May 13, 2010

Thursday's Weather Thoughts

Today was certainly a much better day across Greater Nebraska as far as the weather is concerned, but temperatures are still well below where they should be for this time of year.

Highs today were generally in the 50’s, but we should be seeing highs from the upper 60’s to lower 70’s across the area, and it may be Monday before we see temperatures that are at seasonal levels. Breezy conditions added a bit of chill also, but the partly sunny skies did make it feel much better than yesterday.
However, we still need to get through one more frosty night tonight before we are finally done with the very cool temperatures, hopefully for the rest of the season. Skies will be partly cloudy tonight and lows will reach the lower 30’s, so frost and even some freezing is possible, and Frost Advisories are in effect for most of the viewing area.

Friday will be a bit milder but still below average with highs in the lower 60’s under partly sunny skies.

A disturbance moving eastward our of the Rockies will cause increasing cloudiness Friday night, and showers and thunderstorms are possible Friday night though the day on Saturday. Highs Saturday will also trend a bit downward and top our in the upper 50’s.

By Sunday, the disturbance will be moving eastward but may still affect the region with isolated thunderstorms, especially the farther east you go. Highs on Sunday will recover to the lower 60’s.

Even milder air should get into the area next week, but there will be chances of showers and thunderstorms as the region will be dominated by weak weather systems.

Mike

Wednesday, May 12, 2010

Wednesday's Weather Thoughts

Things can only get better from here weather-wise – and they will.

Today’s weather was more typical of mid-February than mid-May, and highs across Greater Nebraska failed to get any higher than the middle 40’s. Most of the rain exited the viewing area by mid-afternoon, but clouds, mist and some fog, along with a bit of a breeze certainly took away any thoughts of Spring.

Tonight will remain cloudy and misty, with some patchy fog also, with lows falling to the lower 30’s. While it appears that most lows will not fall below freezing, it will be a close call so you may want to protect any sensitive plants outside.
Thursday will start with some clouds and maybe some patchy fog, but by afternoon there will be more in the way of sunshine, and highs will respond by climbing into the upper 50’s. However, a stiff breeze will make it feel cooler.

There is some concern for a frost or freeze on Thursday night if skies become mainly clear and winds are light, so stay tuned to later forecasts for this possibility.
Beginning Friday, temperatures should continue to climb closer to the seasonal averages which are now in the lower 70’s. The next chance of showers and thunderstorms will come Friday night and Saturday as a disturbance approaches the region. Temperatures will stay close to the seasonal norms through the beginning of next week.

Mike

Tuesday, May 11, 2010

Tuesday's Weather Thoughts

What has happened to Spring?

Temperatures today were once again well below average – we should be up around 70 degrees but highs today could not get out of the lower 50’s, and stayed in the 40’s over northern areas. And unfortunately, Wednesday will be a reminder of winter.

Another area of low pressure is developing over southeast Colorado this evening, and is already producing rain and higher elevations snow across much of the northern and central Rockies. This low will track pretty much as the low that affected our weather yesterday – eastward across Kansas then northeastward into Iowa. Rain will develop out ahead of the low later tonight, and there could even be a thunderstorm. Lows will bottom our in the lower 40’s across the southwest to the middle 30’s to the north and west.

On Wednesday, the low will be over central Kansas and rain will be falling across Greater Nebraska. However, the rain will mix with and even change to wet snow in areas well to the north and west, and areas in the far north and west in Sheridan and western Cherry counties may see at least a few inches of slushy snow, especially on grassy areas. Winter Weather Advisories are in effect for those areas. A few snowflakes may mix in with the rain elsewhere from time to time, but no accumulation is expected. Highs will go nowhere and stay in the middle 30’s to lower 40’s from north to south, nearly 30 degrees colder from where they should be this time of year. Windy conditions will make it feel very raw to be outdoors – certainly not a very springlike day for the middle of May.

Drier weather will begin on Thursday as the low pulls to our east, and temperatures will begin to climb each day, and by the weekend highs will get close to the seasonal averages. In fact, by early next week true Spring weather may finally be back as highs reach the middle 70’s.

Mike

Monday, May 10, 2010

Monday's Weather Thoughts

Today’s weather was reminiscent of the middle of March, and by Wednesday you may wonder if it’s mid-February!

Low pressure moving to our south over Kansas bought thunderstorms to the area last night, and some showers, fog and mist, and cool temperatures, to Greater Nebraska today. Highs only reached the upper 40’s to lower 50’s in most areas.
Tonight will be cloudy, and it will shower from time to time and there may even be an isolated thunderstorm, along with some mist and fog as lows bottom out in the lower 40’s. The showers will end after midnight then it will remain mostly cloudy.
We will be between weather systems tomorrow so expect mostly cloudy skies, but there will be some sunny peeks but no precipitation is expected as highs get into the upper 50’s.

By Tuesday night and Wednesday, a new area of low pressure will get its at together over eastern Colorado, and take pretty much the same track as the current low – eastward over Kansas then northeastward over eastern Iowa. As the low tracks to our south, Canadian high pressure to the north will filter some very chilly air southward into the area, and highs on Wednesday won’t rise much and will stay in the lower to middle 40’s. Temperatures may actually fall into the 30’s as precipitation is falling, and area north and west of North Platte may see some snow at least mix with rain that will be falling, and some areas may actually see a changeover to snow Wednesday morning, and it is not impossible that some accumulation could occur, especially on grassy surfaces.

This low will lose its grip on Greater Nebraska during Wednesday night, and Thursday will see fair weather returning with milder temperatures. By the weekend, more springlike weather should take hold, which will be most welcome.

Mike

Friday, May 7, 2010

Friday's Weather Thoughts

Near record cold temperatures tonight and remaining chilly through the weekend.

Cold Canadian high pressure centered over Montana will move slowly eastward, and by tomorrow a high pressure ridge will be sitting right on top of the Plains. Skies will turn partly cloudy overnight and winds will diminish, but lows will drop to the middle 20’s in many areas so a hard freeze is expected. The record low for North Platte for Saturday is 23 degrees, and we could break the record but right now it appears that we will stay just above, but very cold for this time of year nonetheless. Any sensitive plants and anything else that may freeze such as back flow devices should be protected to minimize problems.

Saturday will still be quite chilly and well below average temperature-wise (highs should be right around 70) as highs only sneak into the upper 50’s under partly sunny skies. However, winds will be lighter than today so it won’t feel quite as cool.

A southerly wind flow will begin across the area Saturday night and strengthen on Sunday, and this will help keep temperatures from falling too much but lows will still get into the 30’s. Mother’s Day Sunday should be partly sunny and quite breezy, and highs should approach 60 which is still well below average. Some showers may affect the area as the southerly flow brings some moisture into the area, but any activity should be isolated and not cause many problems with outdoor activities.

Another storm will affect the area early next week, and this storm may become potent with some significant rainfall.

Mike

Thursday, May 6, 2010

Thursday's Weather Thoughts

Unseasonably chilly weather is in store for Greater Nebraska from now through the weekend and beyond.

A frontal system crossing the region this evening will set off a few showers and perhaps an isolated thunderstorm as it passes until about midnight, then skies will turn partly cloudy and lows will fall to the lower 30’s with breezy conditions, so a cold night for May. But things get even colder from here.

Friday will be fair with a mix of sun and clouds, but highs will struggle to reach the middle 50’s, and winds gusting to 35mph will make it feel much cooler so a jacket is the order of the day.

The coldest part of the forecast is from Friday night into Saturday morning when low in most areas fall well into the 20’s, so a hard freeze is likely and protection should be taken for any outdoor plants, and also anything that can freeze such as Back Flow Devices. The record low for Satuday is 23 set in 1907, and there is a possibility that we could at least tie the record but right now that is not expected.
Mother’s Day Sunday will get a bit milder as highs approach 60 under partly sunny skies, but breezy conditions will also add a bit of chill to any outdoor plans.

To get a better sense of how chilly the temperatures will be in relation to what we typically should expect, take a look at the graphics below. The red line is what we should typically expect, and the blue line is the forecasted temperatures for each day.




































As you can see, we will be well below average for the next 5 days for highs, and lows will be well below average early on but will get up to or even a bit above average early next week before likely trending down again later next week.

A developing storm over the Rockies will bring the threat of rain for early next week with more cool temperatures.

Any Sustained Warmth Soon?

Viewers around town have been asking if and when we can expect some sustained warm weather. Now that we are into the month of May, it would seem plausible that truly warm weather is right around the corner. Not so fast!

Unfortunately, the forecasted jetstream pattern is such that Greater Nebraska has a greater chance of seeing sustained cooler than average temperatures rather than warmer than average weather that will stick around for a while. Through at least mid-month, the typical jetstream pattern will be one of a trough in the western and central states, with a ridge in the east. What that means for us is that any cold air still up in Canada will be able to come southward into the Plains, while warmer than average temperatures are in store for the Southeast, Ohio Valley and Mid-Atlantic States. We won't see any sustained warmth in Greater Nebraska until more of a ridge develops and locks in over the Plains states, but that doesn't look like it will happen for at least the next couple of weeks.

On the bright side, at least the threat of severe weather will be reduced while this pattern remains, which is certainly some good news.

Mike

Wednesday's Weather Thoughts

More changes to occur beginning Thursday!

Clear skies early tonight will yield to some clouds overnight as lows bottom out in the middle 30’s. Thursday will see a mix of sun and clouds, and an afternoon shower or thunderstorm could occur with highs in the lower 60’s. Then get ready for some very chilly weather for May!

Temperatures should fall below freezing over many areas overnight Thursday into Friday morning, and Friday will become windy and very chilly with highs struggling to rise to the middle 50’s under partly sunny skies. But the coldest night of all should be Friday night into Saturday morning as lows drop well into the 20’s across Greater Nebraska, so a hard freeze is likely which means that any plants, back-flow devices, etc., should be protected.

Don’t expect much recovery in temperatures over the weekend as highs stay in the middle 50’s both Saturday and Sunday, with lows in the 30’s Sunday morning with partly sunny skies and breezy conditions continuing. The next chance of showers and thunderstorms will come early next week, and highs will slightly rebound into the lower 60’s.

Mike

Tuesday, May 4, 2010

Tuesday's Weather Thoughts

Windy and dry conditions prevailed across the viewing area today as highs reached the middle 60’s north to 80 south. However, temperatures began to drop during the afternoon behind the cold front that brought the gusty winds to the area.

The winds will diminish later tonight, and lows will drop into the lower 30’s under mostly clear skies.

Wednesday will start chilly, but will turn pleasant during the afternoon as highs get into the middle 60’s with plenty of sun and light winds.
Changes will begin Thursday as low pressure developing over Colorado begins to affect our weather. We can expect a few showers during the afternoon and evening with highs around 60.

The shower threat will end after a cold front presses through Thursday night, and Friday through the weekend will be fair but unseasonable chilly with highs only in the 50’s and lows in the 20’s, so plants will need to be protected, as well as any back flow devices.

It will turn milder early next week but with a chance of an afternoon thunderstorm as highs rebound into the 60’s.

Mike

Monday, May 3, 2010

Monday's Weather Thoughts

A very changeable week of weather is coming for Greater Nebraska!

Today was a sunny and pleasant day overall after we got rid of the morning chill, and highs rose to the upper 60’s to lower 70’s. Tonight will be mainly clear and not as cold as recent nights with lows in the 40’s.

Tuesday will be another sunny and mild day, but winds will become quite gusty during the afternoon and evening behind a cold front, and may approach 40mph and higher in some areas, so Wind Advisories and High Wind Watches are in effect. The windy conditions, coupled with low humidity and dry brush will increase the fire danger, and a Fire Weather Watch is also in effect.

Wednesday will be another tranquil day but it will be about 10 degrees cooler with highs in the 60’s. Then systems developing to our north and our west will bring a chance of some rain beginning Wednesday night and extending into Friday, and as colder air filter in the rain my mix with, and perhaps even change over to a bit of snow in some areas especially Thursday night. However, no accumulation is expected.
The weekend will then start out fair before the next western system brings a chance of some afternoon storms on Sunday and Monday.

Mike
