KFVS12 News & Weather Cape Girardeau, Carbondale, Poplar BluffBrian's Weather Summary

Rapid warming....

Significant changes going on in large-scale pattern which will bring much warmer (and more humid) weather to the Heartland by the upcoming weekend.

Today will be very breezy and much warmer as we get placed between a passing low pressure area moving through the plains and high pressure over the southeast.  Dewpoints will be slowly increasing too but still won't be too bad until the weekend.   Fire danger will be high today.

Hot, hazy, humid...

Three H's will be in place this holiday weekend as an upper ridge develops over the southeastern U.S.    With afternoon temps above 90° and dew points close to 70°, it's going to seem more like the 4th of July weekend than Memorial Day weekend.  In fact record highs in the mid 90s look possible both Saturday and Sunday.

In terms of rain chances,  Saturday looks to be pretty much nil thanks to the upper high.  By Sunday it may weaken for an isolated T'storm or two...and then by Monday the upper ridge begins to break down which should allow for at least a few afternoon or evening T'storms.

Best chance of showers/storms looks to be Monday night into Tuesday as a weak front slides through and the flow aloft becomes westerly again.

Indications are that the pattern will back off to become a bit cooler and more active by late next week and into the first weekend of June.
