Synopsis: Coastal low pressure system will continue to slide up the mid atlantic coast, bring snow to portions of eastern PA into tomorrow. As this system departs, upper level ridge will move in and dictate our weather through early next week.
Short Term: Light to moderate snow will continue to fall in southeastern PA, as a upper level trough phases with the southern branch of the jet and allows for the deepening of a coastal low. This nor'easter will bring minor snow accumulations to the Philly metro, but accumulating snow will not slide any farther west. Conditions will clear out during the day Thursday. Broad northwest flow will keep temperatures well below normal, especially as we get into tomorrow evening.
Long term: Upper level ridge will move in by Friday and deepen with time. Southwest flow will allow a general warming trend into the weekend and beyond, especially late in the period. Tranquil weather will be the story, as surface high pressure takes hold. Strond cold front will pass through the region early next week, bringing temperatures back down in the long term.
