A WINTER STORM WATCH has been posted for the entire Washington area and points, west, south and east for the day tomorrow. In general terms, we are calling for 2”-4” of snow inside the beltway. Lighter accumulations are expected to the north and heavier accumulations to the south, east and west. These initial snow projections are subject to change as the storm develops and its track becomes more certain.

Cloudy and cold weather continues with areas of rain continuing through this evening. Skies will remain cloudy tonight and tomorrow. And by this time tomorrow, snow will likely be falling over many parts of our area…especially areas south of a line from Leesburg to Annapolis. Even though we are less than 24 hours away from the first flakes, there is still a lot of uncertainty, in our minds, about how all this will work out. Snowfall totals are hard to describe in words. Refer to graphics on our website. I will say all signs point to a sharp gradient in snowfall totals from north to south with this storm system. The storm has not totally formed yet. It will pass far enough south of Washington, it will allow colder air to turn an initial period of rain to snow. This southern track will also keep the heaviest snow south of Washington. This sharp gradient, I mentioned, will mean that Frederick MD may only see 1 inch of snow while Fredericksburg VA may see 6 or 7 inches. Our snow forecast is based on a projected movement of the storm center. Any small change in track could mean a dramatic change in accumulation forecasts.

Whatever happens…clearing skies are forecast for Friday and lots of sunshine for the weekend. Much colder air will arrive next week.
