Our average high at Philly International is 77; we reached 74 at 7am before temperatures fell thanks to the backdoor cold front. There were also some scattered showers and thunderstorms that dropped about two-thirds of an inch of rain(0.61" to be exact) once that front pushed southward across the Mason-Dixon Line.
Overnight it will remain cloudy with some fog and drizzle possible; lows will be in the lower 50s. It will remain mostly cloudy with highs just in the middle 60s with a continued easterly(onshore) wind between 10-15mph. We'll get back toward 70 degrees on Friday, but a short wave to the north will provide clouds in the afternoon through the overnight. Saturday will start cloudy, but once that short wave pushes offshore we'll have a sunny afternoon with highs in the lower 70s.
Come Sunday we'll be in the middle 70s with a sun-filled day and then we're in the lower 80s on Monday before we cloud up ahead of a cold front that will meander for the middle of the week.
