Trough settles directly over the region today… warmer and more humid beginning Thursday through the weekend…

A trough will be fully entrenched over the region today, which will allow temperatures to remain slightly below normal, with highs only reaching a comfortable middle-70s today. It will be a partly cloudy day, and a slight chance exists to see a pop-up afternoon shower, but we only listed a 20% chance for that to occur. Partly cloudy and for the second straight night, you can leave the windows open and give the air conditioner a rest, as comfortable conditions are expected overnight.

Wednesday will also be under the influence of the same trough as today, but we’ll start to moderate a bit as the trough begins to lose its influence. Winds shift to the southwest on Thursday and a ridge attempts to build into the region through the weekend, but it will also be unsettled a few of those times with a couple of fast moving systems moving well north of the region, that will drag a few boundaries through this area. Right now it doesn’t look like it’s raining the entire time, and favors afternoon/evening scattered storms, but most notably and the best chance exists on Sunday. Every other occurrence looks to be isolated at best Friday and Saturday.
