 and certainly before midnight north and east of Washington. Otherwise, warm and muggy with patchy fog into the 70s on your Wednesday. Little fog in the morning otherwise. Hazy, hot, and humid. Heat advisory for highs in the 90s. Heat index values over 100. Strong to severe late-day storms from 4 to 9 p.m. Behind those storms, though, cooler and less humid for Thursday and Friday. Temperatures back in the upper 80s on Thursday. Upper 80s on Friday, maybe a stray shower or storm Thursday, but most of the day is fine. I'm WTOP's Steve Prince of Alley.
