 Severe thunderstorm watch goes until 11 o'clock. I do believe the threat for severe weather is going to be out of here in the next 60 to 90 minutes, and then we're going to get a front through here, and that will take care of any storms. Overnight, behind the front, clearing, turning cooler, and less muggy. All of us will see lows in the 60s. Beautiful day tomorrow, sunshine, breezy, cooler, and less muggy. A high around 80, sunny and pleasant with low humidity on Tuesday, and a high in the low to mid 80s. Right now, EN 91 at Reagan National with a heat index of 102.
