Another very mild day is expected for the Philadelphia and New York City metropolitan areas as high pressure continues to slowly drift into the Atlantic. A strengthening southwesterly wind at all levels of the atmosphere will lead to temperatures rising to well above normal temperatures into the mid to upper 60's, possibly touching 70 degrees in some locations this afternoon.
While pleasant conditions can be expected this afternoon, clouds will start to increase this evening as a cold front slowly approaches. Temperatures will not fall all that much tonight with most locations expecting lows in the mid 40's to lower 50's. There is a slight risk of fog developing late tonight through tomorrow morning due to what's left of the melting snow pack over the interior.
A cold front will move through the Philadelphia and New York City metropolitan areas by tomorrow afternoon with scattered showers expected tomorrow morning on through early tomorrow evening. These showers may produce a heavy downpour at times, but most locations will only have a few passing weak showers followed by a wind shift from the southwest to the west. Temperatures tomorrow will peak into the upper 50's to lower 60's ahead of the cold front before falling rapidly through the 50's and into the 40's in the late afternoon and evening hours.
