Discussion              

It stays mild in the Mid-Atlantic region for today and into the beginning of the weekend, but an Arctic front will reach the area tomorrow and its passage will bring about much colder conditions for Sunday, Monday and Tuesday.  Low pressure is likely to form along the Arctic frontal boundary zone by tomorrow night and this system should generate accumulating snow in the region from late Saturday night into mid-day Sunday. While the odds are against anything too significant, snow accumulations of a coating to a few inches are on the table later in the weekend.  The core of the Arctic air mass will move overhead by Monday and temperatures will be way below-normal for the middle of February.  Looking ahead, the Arctic chill will wane by mid-week, and there are signs for a big time warm-up by late next week although it could be accompanied by rain at week’s end.
