Brian’s exclusive forecast for Baltimore, Washington DC, and Annapolis:
Today: Snow, sleet, and freezing rain changing to all freezing rain. High around 32.
Tonight: Freezing drizzle, then mostly cloudy with a low around 30.
Monday: Becoming mostly sunny with a high in the upper 30s.
The first day of March begins with a Winter Storm Warning (see below) for Baltimore, Washington DC, and Annapolis effective Sunday morning through Monday morning. The warning is an upgrade from a previous winter weather advisory and is being issued to account for the potential of a significant accumulation of ice through this evening. The National Weather Service expect up to 1/4 inch of ice accretion from this system. Snow and sleet this morning may accumulate up to 1 inch before changing over to freezing rain as warmer air aloft overrides colder air at the surface. As the rain falls into the layer of cold air, it will freeze on surfaces and result in icy conditions on roadways and walkways. The ice accumulation may also result in down limbs and power outages across the area. As the area of low pressure moves away from the region, precipitation will come to an end this evening, but temperatures will hover around the freezing point. Consequently, conditions may be icy through the night and into the early morning hours on Monday. Conditions will improve on Monday with afternoon sunshine and highs in the upper 30s to near 40 degrees.
