Cool morning, hot afternoon
After widespread morning lows in the 50s, temperatures will likely rebound to about 90 degrees in the Roanoke Valley on Wednesday afternoon. Very dry air has established itself in the area after the weekend front, and this allows for rapid cooling and warming of the air compared to more humid conditions. We could see the low 90s on Thursday and Friday as humidity also slowly builds. After our June 4-10 heat wave, it's only managed to hit 90 in Roanoke twice in the two weeks since. Our last 90-degree day was on June 16.
The weekend deserves a little attention for severe thunderstorm potential, as an approaching cold front accompanied by some upper-level cold air and wind dynamics will be moving into building heat and humidity. It's a long way off with a lot of details to work out. Several warm to hot, dry days are likely between now and then.
