Discussion
Upper-level energy will slide across the Midwest today and into the eastern US and will contribute to the formation of low pressure near the Mid-Atlantic coastline by early tomorrow. Meanwhile, a cold front will also play an important role in this upcoming snow event as it will slow down as it arrives in the eastern US late today as it will become aligned parallel to the upper-level wind flow (southwest-to-northeast). As a result, snow associated with the frontal system will tend to last for an extended period of time tonight and then low pressure induced snow will fall early tomorrow. The combination of the front and low pressure system should generate 1-3 inches of accumulating snow in the Philly metro region. The timetable for the snow is primarily from late tonight into tomorrow morning with some impact possible for the Wednesday AM commute. It'll stay cold following this system for the latter part of the work week with a reinforcing cold air mass ushered in by the frontal passage, but then a noticeable warm up will occur this weekend.
