The warm conditions from yesterday afternoon where highs rose into the upper 50's to mid 60's, even a few upper 60's, are now exiting into the Atlantic as a cold front exits off the coast. A disturbance along the coast front will keep the threat for showers in the forecast through this afternoon as winds shift to the northwest at 5 to 15 mph. Temperatures will rise slightly into the mid 40's to lower 50's for highs.
High pressure will take hold this evening on through Tuesday with tranquil weather conditions expected. A series of disturbances will pass to the south of the New York City and Philadelphia metropolitan areas on Sunday, however all precipitation is expected to remain south of the region with only a slight increase in cloud cover expected. Temperatures will remain above normal, but only slightly so with lows in the mid 20's to lower 30's and highs in the upper 30's to mid 40's.
A cold front will approach on Tuesday with scattered showers followed by much cooler weather conditions on Wednesday as a Polar high pressure system takes hold. Temperatures will range from the lower 20's to lower 30's for lows and mid 30's to lower 40's for highs.
