Quiet end to the week, but snow moving in Saturday.

Tonight: Partial Clearing & Winds Diminishing

Lows: Mid 20s to Low 30s | Wind: N 5-10 mph

Friday: Partly Cloudy & Seasonable

Highs: Upper 30s to Low 40s | Wind: N 5-10 mph

Saturday: Mostly Cloudy & Cold; Snow Developing Early; Light Accumulations

Highs: Upper 30s | Precipitation: 70%

As the powerful winter storm continues to move farther away and high pressure draws closer, the winds are diminishing. Skies will begin to clear tonight and temperatures will drop. Tomorrow will feature much more sunshine than today and high temperatures will be just where they should be for late December. By late tomorrow night, the next system will be taking shape to the south, returning cloudiness to the region and a chance of snow before sunrise Saturday morning.

Latest computer model simulations make a good case for the snow gradually mixing with, then changing to rain Saturday afternoon in much of the metro area. As in many similar atmospheric set-ups, the changeover may be delayed or may not happen at all in areas farther north and west of Washington. While I do not feel confident enough yet to lay out specific accumulation totals across the region, my thought is 1”-2” across the greater Washington area…as a possibility. I will go out on the limb tomorrow afternoon and be more specific in accumulation predictions. Skies will clear on Sunday and it will be quite breezy and cold. Going to Fed Ex Sunday night to see the Redskins win the Eastern Division of the NFC ? Bundle up!! It’s going to be COLD.
