 Until 11 o'clock. So any storms that do develop over the next several hours could be severe. Looks like this activity will end before midnight, though. Overnight, behind the front, turning cooler and less muggy are lows in the 60s. Sunshine, breezy, cooler and less muggy tomorrow. A really nice day with a high near 80. And the nice weather will continue on Tuesday with more sunshine and low humidity and a high in the low to mid 80s. Right now, Jenny, it's 92 at Reagan National. Heat index 102.
