Here we go again. March is a constant battle between spring and winter. Spring won Saturday. Winter will win Sunday and Monday. Expect snow Sunday night and Monday morning from 2" - 6".
WASHINGTON (WUSA9): After a breezy and warm Saturday afternoon, it'll stay breezy tonight, with some clouds moving in. The breezes are from the north, bringing in colder air. As a result, Sunday will be much cooler, but dry through most of the daylight hours. However, a storm will approach from the southwest during the day, and we could see a few raindrops or melting snowflakes before sunset. The real threat arrives on Sunday night, with the rain turning to snow throughout the Metro. The snow will accumulate on grass and other untreated surfaces, but roadways will still be warm, so the snow will melt on contact. Still, St. Patrick's Day looks messy and raw, with highs mainly in the 30s.
Early and late season snows favor melting on roads and accumulations on grassy surfaces. March snows are also usually the heavy, wet snow as opposed to the dry fluffy stuff. This storm looks to bring wetter snow south of the Beltway, and more powdery snow to the north. However, this will be balanced by the greater amount of moisture staying to the south, so there shouldn't be a huge difference in snowfall totals across much of the DMV.
Timing: Rain & snow could be moving in by sunset on Sunday and a complete changeover to snow is likely to occur right after sunset. The Monday morning commute will be the worst part of this system, and that's why Monday is a Red Alert Day in the First Alert weather center.
