An approaching strong cool front will close in on the east coast by later tonight and the result will be showers and thunderstorms in the DC metro region at just about anytime from mid-day on and any storm that forms ahead of the front can be on the strong side with gusty winds and brief downpours. Temperatures today will be knocked down some compared to yesterday due to an abundance of clouds, but they should still manage to climb through the 80’s to go along with the continued uncomfortable humidity levels. Big changes will follow the frontal passage, however, for Friday and Saturday.
Canadian high pressure will edge eastward from the Great Lakes region on Friday generating a stiff and cooling north-to-northwest breeze in the Mid-Atlantic region with noticeably lower temperatures and humidity. By early Saturday morning, many Mid-Atlantic locations will experience low temperatures in the 40’s and the big cities along I-95 from DC to NYC will struggle to pass the 70 degree mark on Saturday afternoon. The pleasantly cool weather conditions will continue right into early next week as there should be a reinforcing Canadian high pressure system headed our way and it may turn out that yesterday is the last 90 degree day of the season in many Mid-Atlantic locations.
