10:30 p.m. Update: Dulles Airport is reporting light snow in its latest observation, and we’re getting reports of various precipitation types (rain, sleet, snow) from readers across the area this evening as light precipitation lingers especially from around D.C. toward points north and west. Regardless of what’s falling where you are, temperatures are falling and that means an additional light coating of snow or ice is possible over the next few hours, mainly in the colder north and west suburbs, before precipitation peters out. Some icy spots are likely as well north and west of town overnight into the early morning.
Today’s rainy, “sleezy” (mix of snow, sleet and freezing rain) storm is moving out and leaving multi-colored skies in its wake. Clearing will be slow and some patchy shower activity remains possible overnight. Watch out for icy spots which may form, especially north and west of the beltway. On Thursday, we clear out, but it’s very windy, with gusts to 50 mph possible.
Through Tonight: Steady rain ends between 5:30 and 7 p.m. but some spotty showers may linger a bit longer on the north and northwest side of town. It’s chilly and normally colder locations north and west of the beltway (places like Oakton, Warrenton, Ashburn, Leesburg, Darnestown, Germantown, Gaithersburg, Frederick, Clarksburg, etc) may well see slick spots redevelop this evening and overnight. Lows range from the upper 20s in the colder suburbs to the low-to-mid 30s downtown.
Thursday: A rain or snow shower (mainly north and west suburbs) is possible early in the day, then it becomes partly to mostly sunny but windy and cold. Highs range from the upper 30s in the colder suburbs to low 40s elsewhere. Winds are very strong, sustained at 20-25, with gusts of 40-50 mph possible - from the west and northwest.
Saturday storm: Models - while still subject to change - continue to support the idea of some snow, mixed precipitation or rain Saturday. My current interpretation of available information suggests this will be a light to moderate event at most.
Once again, temperatures are marginal for snowfall, so it’s not 100 percent clear we get snow rather than some sort of mix or even light rain. But the general track of the low pressure system - as forecast by the models - typically would be a snowier one.
Our winter weather expert, Wes Junker, will take a detailed look at the storm potential in a post tomorrow. For what it’s worth, NOAA’s Hydrometeorological Prediction Center assigns greater than 70 percent chance of 1 inch of snow Saturday. I think this is overdone.
As for today’s event, this is what snow lovers are left pondering...
