Snow for DC Late Tomorrow

January 16, 2013; 8:28 AM ET

Wednesday 10:45 a.m.

On Monday, it warmed to the 60s. Yesterday it stayed in the 40s as soaking rain approached. Now there are prospects for accumulating snow and treacherous travel conditions for large portions of Virginia and the southern and central parts of Maryland and Delaware.

Two weather makers are poised to threaten the first major snow of the season for DC: a low pressure area moving northeastward from the Gulf of Mexico, and a cold high pressure area that sends cold air south from New York state and New England. This video shows how the storm and high pressure area may progress. It is based on last night's 1 a.m. GFS run. Newer models this morning showed some snow getting all the way up to the New York City and Boston areas later tomorrow night!

Meanwhile, the storm that caused mainly rain from DC to NYC last night had enough cold air with it to create miserable driving conditions from Philadelphia's far northern suburbs to much of the New York City region this morning as rain, freezing rain and sleet dominated the morning commute.

After a temporary warmup this weekend, bitterly cold air from the remote frozen hinterlands of the Arctic will pour south to give the Great Lakes and Northeast their coldest weather so far this season. This map shows the flow aloft forecast for next Monday night. It is easy to see why cold air is on the way.
