HEAT ADVISORY Remains in effect in the DMV

WASHINGTON DC — A strong upper-level ridge will remain over the eastern U.S. through Wednesday, keeping the combination of high heat and very high humidity in place.  A Heat Advisory will remain in effect for areas roughly along and east of I-95 through 7 PM today, and will be in effect tomorrow for the same areas from Noon through 7 PM. The heat index during these times will reach 105 degrees.

An upper-level wave will cause the ridge to buckle on Thursday, allow a cold front to slowly move through Virginia on Thursday. This front will result in slight cooling and will be a trigger for showers and storms Thursday afternoon. A few storms will be possible again on Friday as the front remains draped over the region.

The upper-level ridge will become re-established over the region this weekend, with hot and humid weather expected Saturday through Labor Day.  A few storms will be possible each afternoon, but no days should be a wash out.
