***Significant winter storm for the Mid-Atlantic region from Friday PM into Saturday PM***

A fresh infusion of Arctic air from southeastern Canada will set the stage for a significant winter storm in the Mid-Atlantic region from Friday afternoon into Saturday. The cold air mass will be anchored by strong high pressure over SE Canada which will stay in place during the late week/weekend event. The storm will bring accumulating snow across the northern Mid-Atlantic and a mixed bag of precipitation across the southern Mid-Atlantic. Travel conditions will deteriorate rapidly once the precipitation gets underway on Friday afternoon and will remain difficult right through Saturday with temperatures at or below freezing in many areas.

Here is a breakdown for the I-95 corridor:

NYC metro, central/northern NJ, east-central and NE PA: primarily a snow event with accumulations in the 5-9 inch range, some sleet can mix in at times, surface temperatures stay below freezing through the event

Philly metro, northern DE: snow and sleet should dominate with some freezing rain possible; especially, later in the storm, snow accumulations in the 2-5 inch range and there might just be a thick layer of sleet put on top of the snow, I don’t expect surface temperatures to get above freezing through most of the event.

DC metro: a combination of rain, freezing rain, and sleet, watch for an ice buildup; especially, across the normally colder northern and western suburbs.
