Arctic Front Will Usher In Coldest Air of Season and Gusty Winds

A strong cold front will cross the Washington Area this evening ushering in the coldest air of the season thus far. Winds may briefly gust between 45 and 55 mph along with heavy downpours and a clap of thunder as the cold front crosses your community.

Behind the front, gusty winds will continue through the midday hours on Monday while accumulating snow falls across the Allegheny Highlands including places like Garret county Maryland.

Saturday Evening Update on Sloppy Sunday

The latest forecast models all show a period of moderate to heavy precipitation moving into the Washington Region on Sunday afternoon and continuing through the evening before tapering off just after midnight on Monday. Temperature profiles are modest for snow in the immediate D.C. Area where I would expect at most a coating to one inch.

The northern Shenandoah Valley to Leesburg and Baltimore will likely pick up one to three inches of snow with four to six inches (Winter Storm Warning Criteria = 5″ +) across northern Loudoun county in Northern Virginia northeastward toward the Pennsylvania State line.
