Sunday was another cloudy day as a short wave was progressing eastward, but was also interacting with a stationary front just offshore. We reached a high of just 82 at Philadelphia International Airport in the afternoon after a low of 70 in the morning. Officially a trace of rain fell at the airport and the "heaviest" rainfall amounts were closer to the shore with 0.10" there. There was sunshine by the afternoon as some low level clouds eroded, but there's still mid-level clouds that will linger around overnight; this will keep temperatures in the middle and upper 60s.
Clouds will linger in the morning on Monday, but push eastward by the afternoon(so the further east you go the longer it will take for the sky to clear out); highs will be in the lower 80s with a northeasterly wind gradually shifting from out of the south by the late afternoon and evening. After an overnight low in the upper 60s with a mainly clear sky we'll have that southerly wind on Tuesday propel temperatures into the upper 80s as well as the humidity pushed up there as well.
Wednesday will be into the lower 90s and then late in the evening there will be clouds leading to showers and thunderstorms through the overnight with lows in the middle 70s; a cold front will be progressing southeastward on Thursday so highs will be in the middle to upper 80s with scattered showers and thunderstorms continuing until everything clears out overnight.
This will set us up for a great Friday with sunshine and lower humidity as highs will be just in the lower 80s; Saturday will be in the middle 80s, but then the muggy weather returns for Sunday with highs approaching 90 as well as afternoon showers and thunderstorms.
