It was an overcast day with light rain in the afternoon; after a low of 47 at Philly International Airport we reached 50 with an onshore wind all day and even some light rain(0.03") by the 5pm climate report(a final report is issued around 2am).
Overnight lows will be in the lower to middle 40s with moderate to heavy rain which will last through Wednesday as highs will be around 60. Throughout the day there may be 1-2" of rain possible so flash flood watches are posted through the region for that region. A warm front will push through overnight into Thursday so temperatures will rise a few degrees with continued showers and even thunderstorms! This will lead to highs in the afternoon on Thursday in the middle and upper 70s! There is still a risk of showers and thunderstorms in the afternoon as the cold front pushes through overnight.
Friday will be in the upper 60s with a partly sunny sky and an outside chance for rain as the upper level low pushes eastward; over the weekend we stay in the upper 60s with a mixture of sunshine and clouds as another disturbance passes by to the north, but there may be some showers the further north and west you go.
