Monday, May 20 Morning Forecast Discussion

By  | 

Happy Monday! We are off to a warm start to the new work week with temperatures mainly in the mid-to-upper-60s across our area this morning. Rain and cloud cooled air kept us in the 70s yesterday, but partly cloudy skies are in store for our Monday with highs in the upper-80s to right around 90. There will be a chance of a pop-up shower or storm mainly in the afternoon hours today thanks to a warm front lifting up from the south and then stalling out to our north. Many of us; however, look to remain dry today.

With the stalled out frontal boundary to our north, I can’t entirely rule out a rogue shower or storm on our Tuesday due to the fact that we will still be in the warm and moist sector of the frontal system. At the same time, high pressure will be building on in from the south and east trying to keep us dry. My forecast calls for the high pressure winning out with us staying dry on Tuesday, but I’ll re-evaluate that decision once I see how showers and storms develop today.

The high pressure system that I mentioned moving in on Tuesday will become our main story as we head throughout the rest of the work week and into the Memorial Day weekend. It will help keep us dry through at least Sunday with temperatures warming up through then as well. Speaking of temperatures, low-90s for highs return tomorrow and last through Thursday and then highs will be in the mid-90s Friday through Sunday. Morning lows will generally be in the upper-60s through Saturday morning, with lows in the 70s by Sunday. Heat index values may approach the 100 degree mark by the last few days of this forecast period as the humidity factor will begin creeping up, especially during the weekend.
