Heating up quickly by midweek

RALEIGH, N.C. (WTVD) -- First Alert: After a cloudy and cool start to the week, another heatwave begins Wednesday and lasts through the upcoming weekend.

It'll be a mild evening with plenty of cloud cover. A mostly cloudy sky is expected overnight with lows in the 60s.

Conditions improve Tuesday as temperatures begin to warm and some afternoon sunshine returns. A stray afternoon shower can't be ruled out, mainly south of the Triangle.

By midweek, a strong ridge of high pressure will build eastward, setting the stage for a significant warm-up. Temperatures climb Wednesday before peaking Thursday and Friday, when highs could approach 100 degrees. Heat index values may near Heat Advisory criteria during the hottest part of the day.

The heat lingers into the weekend, although a few afternoon thunderstorms are expected both Saturday and Sunday.
