We are now entering the official final weekend of summer (although meteorological fall started a few weeks ago) and although its chilly today a warm up is on the way for Saturday and Sunday that will make it the perfect final weekend of summer to go outdoors, camping or to the beach!
Todays highs will be stuck in the 60s area wide as a cold front that passed through overnight has bought a strong but brief push of polar air with it, lows tonight will mostly be in the 40s for a good chunk of the area, with low to mid 50s in urban areas and southern coastal areas , a few upper 30s are possible in the usual cold spots of NE PA and valleys etc.
Tomorrow as high pressure shifts east, winds will turn more southerly, brining a warmer more moist air mass into the region, with highs in the 70s for most of the area, with upper 60s to low 70s over the interior, mid 70s along the coast and mid to upper 70s in between , lows by Sunday morning will only fall into the upper 50s to mid 60s under increasing cloud cover
Sunday will be the warmest day we have seen in a little while and will be the warmest of the next 7-10 days as southerly winds increase ahead of a cold front, with highs in the mid 70s to lower 80s with a few mid 80s likely in urban areas
Sunday late afternoon and evening a cold front will approach but an offshore storm system is expected to rob most of the moisture associated with it, so while an isolated shower or storm can be expected, especially further north and west, a lot of the area should experience a dry frontal passage
Temperatures will take a tumble by Monday as another trough drops southeast with highs most of the week in the mid 60s to low 70s and lows in the mid 40s to low 50s , could be a bit cooler around mid week with a reinforcing shot of cool air before a warmer pattern takes hold for late September.
