10:50 a.m.: Our biggest event of the winter so far has been a relatively small one. But has produced some snowy/icy scenes nonetheless (pics from McPherson Square, DC & Centreville, VA). The main streamof precipitation is now well southeast of the area, with one more batch to the southwest that may clip Stafford and Charles counties as it heads east. Temps are still mainly near or below freezing, so watch out on those side roads.

9:40 a.m.: Some snowfall totals gathered by NWS: Chevy Chase, 1”; Annapolis, 0.5”; Germantown, 1.7”; Barcroft (Arlington County), 0.6”; Alexandria, 0.8”; Vienna, 0.8”. Local ice totals are generally around .10-.15”

8:45 a.m.: Much of the metro area from northern Fauquier, northern Prince William, Fairfax, central Prince George’s counties and to the north are largely precipitation free. The band of mainly freezing rain and rain south of there may creep north a bit as the storm continues to wind down over the next few hours, but probably with not much additional impact, especially on main and treated roads.

8 a.m.: Round two of this winter event has largely managed to skirt the immediate D.C. area to the north and to the south. Still, freezing drizzle has led to additional iciness even in places that have not seen sustained freezing rain this morning. Ice accumulation on top of snow and sleet appears to mainly be about a trace to 0.10” locally, with more north and west. Temperatures that are slowly rising are still below freezing across a majority of the area, though that should begin to change in the next few hours as precipitation ends.

Radar indicates that the main plume of moisture will continue to stay south of much of the region, though southern reaches of Prince William, Stafford, Charles, and Prince George’s are at the risk of occasionally seeing more in the way of steady freezing rain (or rain as these areas warm first). Another area of steadier freezing rain is lifting away, impacting the Baltimore area and to the northeast.

Otherwise, precipitation should be spotty and drizzly at least in the near term. There’s a possibility more widespread activity temporarily develops in a way that can impact the immediate area, but it’s increasingly less likely as time goes by and we're generally in wind-down mode. While reports indicate that main roadways are largely wet, caution is still advised if driving around the next few hours. Additionally, many sidewalks are untreated and slippery.
