Fall Begins Wednesday Night But Summer-like Weather Will Continue

Autumn begins Wednesday night at 10:09pm CT, but the weather tomorrow will be anything but Fall-like.

The front that caused thunderstorms across Greater Nebraska last night has stalled to our south and east, and currently extends from southeastern Nebraska into central Colorado. The front will begin to move slowly northward and eastward tonight, and by tomorrow morning should be located over southern parts of the viewing area. It should then clear southern areas during the morning hours and northern areas by early afternoon. As the front moves approaches, east to southeast winds ahead of it will cause clouds to increase tonight, and there is just a slight chance of a thunderstorm, especially over southern parts of the viewing area. Lows will drop into the 50’s.

The warm front should be located near the Nebraska/South Dakota Border by tomorrow afternoon, and this will allow gusty southeasterly winds and partly sunny skies to raise temperatures well into the 80’s over southern areas, but may hold in the 70’s over the north where more cloud cover may hold on until late morning. A couple of areas could even see the 90 degree mark, so a quite warm day for the first day of fall. It will become breezy with southeasterly winds gusting up and over 30mph at times. There could be an isolated storm anytime, but most thunderstorm activity will hold off until later in the day.

An upper-level trough now moving into the West Coast will move eastward to the Intermountain Region Wednesday evening, and move through the Plains during Thursday. This trough will tap moisture moving northward from Mexico into the Southwestern U.S. and move it northward into the Central Plains. In the meantime, an area of low pressure on the front now over northeastern Wyoming will move eastward into northern Nebraska during Thursday, and drag a cold front through the region. All of these factors will combine to cause the likelihood of scattered thunderstorms, some which could be severe, and some heavy rainfall beginning Wednesday evening and extending into Thursday morning. Lows overnight Wednesday will be near 60, and highs Thursday will crest in the 70’s under some afternoon sunshine.

But Friday and the weekend, and even beyond, is liking sunny and beautiful with summer-like temperatures continuing with highs near or just over 80.
