BALTIMORE — Get ready—our first major heat wave of the summer arrives on Wednesday.
A Heat Advisory goes into effect from 11 AM to 8 PM as afternoon temperatures climb to around 100°. When you factor in the humidity, it'll feel more like 102° to 108°. Even after sunset, there won't be much relief, with overnight lows only falling into the 70s.
Most of Wednesday will stay dry, although a spotty afternoon thunderstorm could pop up, especially closer to the Chesapeake Bay.
The hottest weather arrives Thursday and Friday, when an Extreme Heat Watch is in effect. Heat index values could top 110°, making this our most dangerous stretch of heat so far this summer.
By the Independence Day weekend, the pattern becomes more active. Scattered afternoon and evening thunderstorms are expected to develop, and some could become severe with damaging wind gusts, large hail, and frequent lightning.
