A Hot & Humid Weekend Coming Up

A weak cool front passed through Greater Nebraska today, but about the only change in the weather was a wind shift from a southerly direction to a northeasterly direction. This front will do little to cool us down or reduce humidity levels over the weekend, and as winds veer to a more southerly direction again tomorrow, expect the hot and muggy conditions to continue.

Tonight will be partly cloudy, and there is a slight chance of a thunderstorm especially over our southern and western areas with lows into the middle to upper 60’s.

But both days of the weekend will feature more heat and more humidity, and it will be breezy with only a slight risk of a thunderstorm Saturday and the chance of a late day storm on Sunday, so most outdoor plans should be fine. Expect a mix of sun and clouds both days with highs into the 90’s, which will feel a bit hotter because of at least moderate levels of humidity.

The next chance of any widespread thunderstorm activity should come Sunday night into Tuesday as another front, along with a strong disturbance travelling along it, approach the area.

Enjoy the weekend!

Storms Tonight Then Hot Into The Weekend

Today was very warm and humid across Greater Nebraska, and a warm and humid night is in store along with a few thunderstorms, especially over our northern zones.

A Tornado Watch is in effect for Cherry County until 10pm CT, and any storm in our northern counties this evening can become severe with large hail, damaging winds, and perhaps an isolated tornado. Over the remainder of Greater Nebraska, skies will be partly cloudy tonight with the risk of an isolated storm with lows near 70 with light winds.

Friday will be another very warm to hot day with partly sunny skies and highs in the 90’s once again. A weak cool front will be dropping southward across the area during the day switching winds from southerly to northerly, and there is slight risk of a thunderstorm just about any time.

The front will dissipate to our south by Saturday, and since temperatures behind the front are not much different from what we are currently experiencing, and since southerly winds will quickly return during Saturday, highs both weekend days will be in the lower and middle 90’s. There is a slight risk of a thunderstorms Saturday, and a late day storm is possible on Sunday, but outdoor plans should not be severely affected.

More widespread thunderstorm activity is possible Sunday night and Monday as another front approaches.

Stay tuned to KNOP and log into KNOPNEWS2.COM and go to our WeatherActive radar to monitor tonight’s thunderstorm activity.

Another Visit From Last Evening's Front On The Way

Today was a much cooler day than yesterday’s hot weather, but the front that cooled us down will be coming back for a return visit, and will warm us up again Wednesday.
Highs today topped out in the 80’s, and with sunshine it was a pleasant day.

However, some showers and thunderstorms are already evident on radar from the Nebraska Panhandle west and south, and anyone can see a thunderstorm this evening and tonight as the front to our south and west pushes north and east towards Greater Nebraska. Otherwise, skies will be partly cloudy with mild lows in the middle and upper 60’s.

The front will push through tomorrow morning, and southerly winds will direct warmer air into the region once again, although not as hot as earlier this week. Highs will reach the low to perhaps middle 90’s under partly sunny skies. There is also a slight risk of a storm, especially over northern areas which will be closer to the front.

Expect this front to waver north and south across the area through early next week with temperatures averaging near normal from the middle 80’s to middle 90’s for highs and perhaps a bit higher than normal for lows – from the low 60’s to perhaps lower 70’s.

There is also a daily risk of at least isolated thunderstorms, though right now the weekend is looking a bit better than it did yesterday with perhaps only isolated storms as opposed to more widespread activity. The more widespread activity may wait until Sunday night into Monday as a strong disturbance rides eastward along the front which should be over the area at that time.

After Today's Heat, A Bit Cooler Wednesday

Highs did cross the century mark in Valentine before a cold front passed through, and may have at Imperial where the high was at least 99. Humidity is moderately high especially over eastern areas so heat indices were over 100 in some cases.

The cold front that is now past Valentine will cross the remainder of Greater Nebraska this evening and overnight before stalling just to our south over northern Kansas. As the front moves through, it may spark a stray thunderstorm in a few spots, but nothing widespread is anticipated. Skies will be partly cloudy with lows in the 60’s, and it will be a bit breezy.

Wednesday will be a nice day with mostly sunny skies and highs reaching the middle to upper 80’s with a pleasant breeze.

As the front tries to return north as a warm front later tomorrow through Thursday morning, it may produce a few isolated storms from very late Wednesday evening into the overnight.

By Thursday afternoon, the front should be located to our north allowing warmer and more humid air to flow in once again. Skies will be partly sunny and there is a risk of an isolated storm with highs in the 90’s.

This front will then waver north and south over the area through early next week, allowing for the chance of thunderstorms daily. The best chance looks to occur over the weekend as a strong disturbance moves along the front, so more widespread scattered storms may occur especially from later Saturday into Sunday morning. Highs will generally be from the middle 80’s to the middle 90’s through the period.

Another Changeable Week Ahead

After a fair and pleasant weekend, today turned hotter with highs in the lower and middle 90’s across Greater Nebraska. And Tuesday is shaping up to be a few degrees hotter.

High pressure over the Great Lakes is circulating a hot and moderately humid southerly flow over the area, and this pattern will continue through the day on Tuesday. After a mainly clear and mild night tonight with lows in the upper 60’s, Tuesday will see sunshine quickly send readings through the 70’s and 80’s and into the 90’s by early afternoon. Highs will reach the middle to upper 90’s by late afternoon, and the extreme southwestern Nebraska typical hot spots like Imperial may reach the century mark.

Humidity levels should remain moderately high, so heat indices could touch or exceed 100 tomorrow afternoon.

A cold front entering the country via North Dakota and Montana will reach northwest Nebraska tomorrow evening, and press through Greater Nebraska tomorrow night. While the front should come through mainly dry, I cannot rule out an isolated thunderstorm, especially over northern areas later tomorrow and tomorrow night.
Behind the front, Wednesday will be cooler with sunshine and highs in the middle to upper 80’s, so a nice day overall.

Unfortunately, the front will stall just south of Nebraska and then waver north and south from Thursday through the weekend. This will allow for the risk of at least isolated storms daily as disturbances ripple along it. The best chance of storms right now looks to be Saturday into Sunday morning as a strong disturbance rolls through. Highs will be generally seasonable in the upper 80’s to lower 90’s through the period with partly sunny to mostly cloudy skies.

Friday's Weather Thoughts

Well our front that has remained to our south all week finally moved to our north during the overnight last night, allowing hotter air to work its way into Greater Nebraska. Highs are generally in the 90’s, with Valentine the warm spot at 96 at 4PM CDT. However, moderate levels of humidity are lifting heat indices to as high as 100 in Valentine, so certainly a hot day.

Low pressure over southern South Dakota will move eastward overnight, and will drag a cool front across the region. Cooler and drier air behind the front will clash with the warm and moist air ahead of it, so some showers and thunderstorms are possible this evening and overnight, especially over the Sandhills where some strong to severe storms are possible. Heavy rain is also possible with any storms, especially over northern areas. Skies will be partly cloudy with lows by morning in the lower to middle 60’s.

But this front will continue to move south tomorrow, and high pressure will build into the area from Wyoming. This will result in a gorgeous weekend for us with sunshine, low humidity, a nice breeze and highs in the 80’s both days, which is perfect for just about any outdoor plans you may have.

As warmer and more humid air tries to move back into the region Sunday night into Monday, isolated thunderstorms are possible. Highs Monday will be in the upper 80’s. The hot weather can be expected from Tuesday into Thursday with highs in the 90’s, along with higher levels of humidity.

Thursday's Weather Thoughts

The front that refuses to release its grip on Greater Nebraska since last week will continue to cause problems for one more day, but then we should be able to look forward to a beautiful weekend.

The front has refused to budge from its position to our south, though it has made some northward progress today, and should continue to move northward tonight and into the day Friday. An area of low pressure moving to our north tomorrow should help push the front northward, then will cause a cold front to press southward through the area later tomorrow and tomorrow night.

In the meantime, the front will cause thunderstorms now to our west over the front range to move eastward into the region, and some of these storms could produce locally heavy rainfall, and a few could be strong to severe at least until about midnight. Lows will be near 70.

Friday will be warmer as the front presses to our north, with highs in the low to middle 90’s under partly sunny skies. As the cold front approaches, a few thunderstorms should develop once again and continue into tomorrow night.

However, the front should press well to our south by Saturday, and high pressure over Wyoming should produce sunny skies with highs in the 80’s, with an active breeze. Sunday should be about the same but perhaps a few degrees warmer. So a very nice weekend is shaping up.
