A weak area of low pressure brushed the Middle Atlantic region today with light, wet snowfall with minimal accumulations. A secondary low developing off the Virginia coastline will become a powerful storm and produce heavy snow with blizzard conditions in eastern New England. Closer to home, light snow showers are currently dissipating and we can expect a cloudy but quiet evening with temperatures in the lower 30s. Gusty winds will make it feel colder at times, and the mercury will dip into the 20s later this evening. Lows by Sunday morning may be as low as the upper 10s in some areas, with lower 20s closer to the bay shore. High pressure will provide bright sunshine on Sunday and Monday, but it will be quite cold with highs each day only around 32 degrees. Overnight lows will drop into the teens again by early Monday morning. Meanwhile, yet another area of low pressure will move across the region late Monday into Tuesday. Precipitation associated with the low will fall in the form of snow from Annapolis northward. Current computer forecast models indicate the potential for 1 to 3 inches of snow in the area, with 3 to 6 inches across northern Maryland. After the snow comes to an end on Tuesday, the sun will break through the clouds and temperatures will climb into the upper 30s to lower 40s. This will signal a break in the winter weather pattern as temperatures will continue to rise throughout the week. Highs on Wednesday and Thursday may break into the 50s and highs on Friday may touch 60 degrees.
