Discussion
Low pressure this morning over the Great Lakes region will transfer its energy to a newly forming coastal low which will only slowly move up the coastline. There will be intermittent snow today and tonight across much of the Mid-Atlantic region with narrow bands of heavy snow likely forming to the northwest of the surface low. There was a lull in the action early this morning, but radar is showing heavier bands already setting up to the north and northwest of the District. Snowfall estimates for the DC metro region are as follows: 1-5 inches with the higher amounts in that range to the north and west of the District (e.g., Montgomery and Loudoun Counties). The snow is likely to be of the wet, slushy variety; primarily sticking on non-paved surfaces except during heavier snow bands which should stick on roadways. Later this week, it’ll turn quite cold and then an even colder Arctic air outbreak will arrive for the weekend and zero degrees is on the table. As the Arctic blast arrives Friday night, there can be some snow shower or snow squall activity as winds pick up noticeably. Looking ahead, another threat for snow is likely early next week – once again falling right around the President’s Day holiday.
