A very cold airmass will set up in place tonight into Friday, and we're already looking ahead to the next winter system Sunday night into Monday.

Clear, Breezy and Cold
Lows: Single Digits to Teens
Wind: NW 10-15 m.p.h.
Sunny and Cold
Highs: Near 30
Wind: SE 5 m.p.h.
Partly Sunny to Mostly Cloudy, Stray Flurry
Highs: Low 40s
Wind: SW 4-8 m.p.h.

The leading edge of a much colder air mass is moving through the area today accompanied by gusty northwesterly winds. Skies will remain clear tonight and with diminishing winds, temperatures are going to drop to extremely low values for the end of February. By morning, air temperatures will range between 5 and 16 degrees. Tomorrow will be bright and sunny but the air will be UNSEASONABLY COLD. We are forecasting high temperatures to remain in the 20s….more than 20s degrees below average. And that is something that seldom happens here, with a full day of sunshine, on the last day of February. Clouds and milder temperatures forecast for Saturday and Sunday.

By late Sunday afternoon or evening, rain will develop across the area. And then from late Sunday night through early Tuesday morning, we will be under the effects of a significant area of low pressure…mostly likely passing near or south of Washington AND an exceptionally cold air mass for early March, north and west of Washington.

As far as what kind of precipitation will fall from this storm.….a wintry mix is expected. The farther north and west you are from DC the more likely the precipitation will be of the frozen variety, the farther south and east you are the more likely it will be more liquid. AND before the storm moves out, it could change to all snow across the region. BTW…computer models continue to show big differences in solutions run to run and from day to day. Stay tuned!
