 Could be another line of thunderstorms later this evening as a cold front comes through. Once again, these could be severe. They will end after midnight. Overnight turning cooler and less muggy. Lows will be in the 60s. And then lots of sunshine, pleasant with lower humidity Monday and Tuesday. High on Monday around 80. Highs on Tuesday around 85. Right now, Sandy, we've got a temperature of 92 at Reagan National with a heat index of 102.
