Brian’s exclusive forecast for Baltimore, Washington DC, and Annapolis:
Tonight: Clear and cold with a low around 15.
Sunday: Cloudy with snow and sleet developing in the morning, changing to freezing rain and sleet during the afternoon. High around 32.
Sunday Night: Occasional rain showers with a low around 32.
Monday: Becoming mostly sunny. Milder with a high near 45.
The last day of February featured bright sunshine over central Maryland, but temperatures were more than 20 degrees below average for this time of year as afternoon highs struggled to reach the 30-degree mark. Cold high pressure over the Northeast states will lay the foundation for a snowy and icy Sunday. As a center low pressure moves to our west, warmer air will override the cold air at the surface. The result will be widespread light snow and sleet developing during the morning hours and continuing into the early afternoon. The warmer air aloft will gradually erode the cold air in place, and precipitation will change over to light freezing rain mixed with sleet at times. Eventually plain rain will fall by Sunday night as temperatures rise above freezing at the surface. At the moment, only about an inch of snow and sleet can be expected, but road conditions may be icy throughout the day as temperatures hover just below the freezing point. The National Weather Service at Baltimore/Washington has issued a Winter Weather Advisory (see below) beginning at 7 a.m. on Sunday.
