Saturday was a mostly overcast day with even some sprinkles to the east while to the west was light to moderate rain; this was due to high pressure in a "squeeze play" between a short wave to the west across Western PA and then a stationary front just offshore. We had a continued easterly wind throughout the day so after a low of 68 we reached a high of 81 at Philadelphia International Airport shortly before 4pm.
Overnight will remain cloudy with a passing shower west of Center City and then a isolated chance of a sprinkle along the shore. Lows will range from the lower and middle 60s with a continued easterly wind. There may even be some light fog possible as well so if you are venturing out I have now warned you.
Sunday will remain cloudy as we are stuck in between these two systems, but we should remain dry as the short wave pretty much will fall apart as it pushes eastward; highs will remain in the lower 80s with a continued easterly wind. The short wave pushes eastward by the overnight and then the stationary front pushes further away from the coast as well by Monday morning so after lows in the middle 60s we'll have afternoon sunshine with highs in the middle 80s.
The wind will continue to come from out of the west, but that changed overnight into Tuesday with a more southerly wind; this means that overnight lows will creep closer to 70 and the humidity returns for Tuesday afternoon with highs in the upper 80s to around 90. Come Wednesday we'll be into the lower 90s with late afternoon to evening clouds as a cold front approaches from the west; this means that early Thursday morning and going through the day will feature scattered showers and thunderstorms with overnight lows in the middle 70s and afternoon highs in the middle 80s.
It's gone by the overnight and then Friday is sunny and drier with highs in the seasonable middle 80s while we warm back up toward 90 going into Saturday with another chance of rain for Sunday. There's still plenty of time to iron out next weekend's forecast, BUT we still half of this current weekend to finish first!
