2:30 PM | Snow showers main threat for late Sunday...very cold air to follow
Paul Dorian
Friday night/early Saturday
Low pressure will push northeastward on Friday from the Southeast US and to a position off the New England coastline on Saturday. Temperatures will be warm enough for rain in the immediate I-95 corridor from tomorrow night into early Saturday before some clearing takes place late in the day. Another system will pull out of the Gulf of Mexico region on Sunday at the same time a dynamic upper-level wave of energy drops out of Canada and over the Great Lakes. It appears the southern system will not hug the coastline as it turns northeast on Sunday and our main player will be the upper-level wave to our northwest associated with another Arctic blast. As a result, snow showers will be the main threat around here for Sunday night and any steadier or heavier snow looks like it’ll be confined to areas well to our northeast.

More bitter cold for next week
Following the late weekend system, more bitter cold air will flood into the Mid-Atlantic region keeping us well below normal into mid-week. In fact, most land masses in the Northern Hemisphere will have a colder-than-normal week as seen on the latest temperature anomaly chart. There are signs for another storm threat late next week or weekend, but lots of time between now and then.
