Low pressure pushes out of the southern states early this weekend and it will head in a northeast direction towards the Mid-Atlantic coastline. Another player in the weekend event will be high pressure over southeastern Canada which will help to lock in some cold air for the Mid-Atlantic region; especially, interior locations. The precipitation is likely to reach the DC metro region as early as late morning on Saturday and it will continue to push to the north and east likely reaching Philly by early-to-mid afternoon and NYC by late afternoon. In terms of precipitation type, it looks like a battle shaping up for awhile in the I-95 corridor between rain, ice and snow with a mixture the likely result in the big cities that will put a limit on total accumulation amounts. Precipitation is likely to continue on Saturday night as rain or a mix of rain and snow and there can be some lingering precipitation on Sunday morning likely in the form of snow.
Preliminary snowfall estimates in DC-to-Philly-to-NYC corridor:
Coating to 1 inch in DC metro, 1-3” in far N/W suburbs
Coating to 2 inches in Philly metro; 2-4 inches in far N/W suburbs
Coating to 2 inches in NYC metro; 2-5 inches in far N/W suburbs
