Discussion
If you had December 9th in your snow pool, you're looking pretty good right about now. Low pressure will push out of the eastern Gulf region later today and head to a position off the Mid-Atlantic coastline by later tomorrow and the big cities from DC-to-Philly-to-NYC will receive their first accumulating snowfall of the winter season. Accumulations on the order of 2-4 inches are likely from late tonight into late tomorrow in and around the big cities with 3-6 inches possible across the Delmarva Peninsula. Residual snow showers are possible early tomorrow night as an upper-level low pushes by just to our north. It stays cold on Sunday and Monday and then the next shot for snow or snow showers will come on Tuesday as a significant cold air outbreak heads towards the Mid-Atlantic region. Temperatures at mid-week will struggle to reach the 35 degree mark for highs following that next snow threat.
