Discussion
Today begins a transition in the Philly metro region from the high heat and humidity of the past few days to much cooler conditions expected here on Friday...the first day of August. A cold front will slowly grind its way through the area later today and tonight as low pressure forms along the boundary zone. Showers and thunderstorms will become numerous for the afternoon and nighttime hours…some of the rain is likely to be heavy at times, some of the storms can be strong, and localized flash flooding is on the table. Showers can linger on Friday morning and the day will be noticeably cooler (jacket weather) with well below-normal temperatures. In addition, an east-to-northeast wind will be quite noticeable in the counter-clockwise flow of air around departing low pressure off the coast. Clearing skies should develop on Friday night and the first weekend of August may turn out to be one the nicest of the entire summer season featuring very comfortable temperatures and low humidity values.
