 This is not severe, but some heavy thunderstorms, which are increasing in intensity across northern portions of Charles County in Maryland. So watch this area, especially in the Waldorf and St. Charles area, in case we get a warning there. Now keep in mind that a severe thunderstorm watch continues until 11 o'clock. Looks like the worst of the weather is going to be along and east of I-95 for the next 60 to 90 minutes. And then after that, I believe the severe threat will come to an end with the passage of a front. Behind the front, overnight skies will clear. It will turn cooler and less muggy, and lows will be in the 60s.
