The next in a series of storms will approach today. This storm will pass by to our west, putting us on the warm side of the system. As the storm moves in and warmer air moves in aloft, cold air will be trapped at the surface east of the mountains. This will result in a wintry mix of precipitation tonight into tomorrow.

Along northern and western Maryland, a Winter Storm Warning has been issued. Expect snow to develop this evening, changing to sleet and then freezing rain. The freezing rain will likely last through the morning before temperatures warm above freezing tomorrow afternoon. Several inches of snow and sleet may fall, followed by up to 1/3 inch of ice from freezing rain.

Further south, into central Maryland, a Freezing Rain Advisory has been issued. Expect snow and sleet to develop this evening and change to freezing rain later tonight. Up to 1/10 inch of ice is possible before temperatures rise above freezing tomorrow morning, changing the freezing rain to plain rain.

Southern Maryland and the lower eastern shore will quickly rise above freezing and see mostly rain.

Mostly Sunny Today; Wintry Mix Tomorrow

As yesterday’s storm pushes northeastward and away from the area, another is taking shape over the Rockies and will move into the area by Saturday morning.

Behind the storm that brought snow, sleet, freezing rain and a lot of plain rain (storm total of 1.31″ here) to the region, skies will gradually clear as northwest winds gust to near 50mph today. A Wind Advisory is in effect until 6pm.

Winds will decrease tonight as weak high pressure builds in tomorrow, providing a calm and tranquil day. Highs will be in the low to mid 40s.

Precipitation will push into the area early Saturday morning. The models are in agreement that the initial precipitation will fall in the form of snow. The models disagree however, on if it will remain snow and how much will fall.
