After a cold, overcast, and raw-feeling Saturday we rebounded nicely on Sunday; there was more sunshine than expected from I-95 southward and after a low of 42 at Philadelphia International Airport we reached a high of 56! That’s six degrees ABOVE average….and guess what? We’ll have another above average day on Monday too!
Overnight will remain cloudy with lows in the middle to upper 40s; Monday will feature mostly clouds, but despite it highs will be approaching the middle 60s. There will also be some light showers in the afternoon as a cold front pushes through. On the other side of the cold front Tuesday highs will just be in the lower 40s; we’ll have very strong high pressure on top of the region while a warm front will approach overnight into Wednesday. That cold air will undercut the warm air allowing some instability(we call this isentropic lift as there will be a temperature contrast over a constant pressured surface), and hence some precipitation. So with this overrunning event I feel that there COULD be some snow and sleet north and west of the I-95 corridor while everyone else would just see a brief mix then a changeover to rain with rising temperatures.
Wednesday itself will be cloudy with some rain showers as highs will be near 50; behind the cold front we’ll be in the middle 40s while another system approaches Friday evening into Saturday that could produce some mixing to the north and west before changing over to rain with highs in the middle 50s by Saturday afternoon.
