Also from NWS:

326 PM EST Fri Mar 11 2022

…WIND ADVISORY IN EFFECT FROM 6 AM SATURDAY TO 1 AM EST SUNDAY…

* WHAT…Northwest winds 25 to 35 mph with gusts up to 55 mph.

The Washington Post’s Capital Weather Gang is a bit more measured in terms of its snow accumulation prediction for Arlington, calling for a coating to 2-3 inches of snow accumulation, with higher amounts north and west.

The storm is expected to start as rain before changing over to snow mid-morning. In such scenarios, snows crews typically do not pre-treat roadways as the treatment would be washed away by the time the frozen precipitation starts.

VDOT said Friday afternoon that its plow crews are ready to tackle the snowy onslaught, while asking drivers to stay at home if at all possible.

VDOT Northern Virginia crews are ready for winter weather that is forecast to impact the region Saturday. The forecast shows precipitation starting as rain and turning to snow. Residents should be ready for high wind gusts and below freezing temperatures.

As always, residents are asked to monitor forecasts and plan ahead to avoid nonessential travel during winter weather.

What’s Happening Now

  • See the Winter Weather Advisory from the National Weather Service for precipitation for Saturday. The forecast includes periods of rain and accumulating snow, as well as increased winds. Please continue to monitor forecasts closely as forecasts can improve or worsen quickly.
  • Crews will mobilize overnight to treat state-maintained roads. Please drive with caution around plow trucks as they are heavy and move slowly.
  • Temperatures are expected to drop below freezing, causing potential icy conditions. Treat anything that looks wet as if it could be icy, especially bridges, ramps, overpasses, and elevated surfaces. If there is snow or ice on roadways, travel is hazardous.
