A weak weather front and low pressure will move through our area later Saturday. Overnight skies are clear for the most part and the air is comfortable.  But very moist air is over us at high levels in the air so it won't take much to fire up some afternoon thunderstorms, especially to the west of D.C. The clouds will break by Sunday afternoon but the chance of everyone getting some needed rains Saturday night is decreasing as the showers are still likely to be spotty rather than very widespread. It'll be back into the 80s next week. Beaches are cooler with southeast winds and even small craft advisories on the Bay, but there is good sailing weather Saturday.
