At mid afternoon, the focus of activity was along the I-66 corridor in Virginia and moving eastward. Current watches and warnings are listed by county in the box above.
Tonight and TomorrowTonight will continue warm and very humid with a 40% chance of thunderstorms through this evening and lows in the mid 70s. Tomorrow will see more clouds than today, a 50% chance of showers or thunderstorms, and highs in the upper 80s.
For the outlook through the weekend, see Dan's post below.
A small, but intense, cell moved eastward a little south of I-66 in Virginia and dumped just under half an inch of rain at National Airport in 10 minutes around 4:00. Another cell was behind it headed toward Manassas and Centreville.
More widespread rain, however, was spread across northern New York state and much of New England, where they don't need any more rain. Golf ball to tennis ball size hail was reported yesterday in Exeter, NH. Severe storms were widespread in southern New Hampshire and eastern Massachusetts.
