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.

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.

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.
