One of the coldest days of the winter is upon us today with early afternoon temperatures in the mid to upper 10s. The cold is impressive considering that the recent snow cover was reduced to patches of snow in yesterday's 50-degree sunshine. Cloudiness associated with the arctic front, which now sits to our southeast, is enhancing the cold by blocking out the sunshine. As we move into the late afternoon hours, temperatures will struggle to reach 20 degrees as cloudiness increases from the south. Meanwhile, low pressure will develop along the arctic front and produce a major winter storm for the southern Chesapeake Bay area including the Tidewater cities of Williamsburg, Wakefield, Norfolk, Cape Charles, and Accomack. In this region, 5 to 10 inches of snow can be expected. Snow will spread into southern Maryland the lower Eastern Shore where 3 to 6 inches of snow may fall in Cambridge, Salisbury, and Ocean City. A Winter Storm Warning is in effect for the Hampton Roads area of Virginia with a Winter Weather Advisory for Maryland's lower Eastern Shore. To the north and west, precipitation will try to encroach on the Annapolis area this evening with a period of light snow or snow showers producing a dusting to an inch. There will be a sharp cut-off between areas receiving snow and those that see nothing more than a few flurries. With temperatures in the 10s this evening, any snow that falls will create slick conditions on roadways and walkways. As the storm system pulls away from the Atlantic coast on Wednesday, sunshine will return to the Middle-Atlantic region but it will be cold with highs only in the 20s (average highs for this time of year are in the middle 40s.) A moderation in temperatures is expected later in the week with highs in the 30s on Thursday and Friday, and upper 30s to lower 40s over the weekend. Another system may bring rain and/or snow showers to Annapolis by Saturday.
On the Maryland portion of Chesapeake Bay, a Small Craft Advisory is in effect through Tuesday afternoon. A Small Craft Advisory is in effect beginning late Tuesday night. Winds on Tuesday will come out of the north at 10 to 15 knots with gusts over 25 knots and waves from 2 to 4 feet. Winds on Tuesday night will come out of the north at 10 knots with waves from 1 to 2 feet. Visibility may be reduced in snow and fog. Winds on Wednesday will come out of the northwest at 10 to 15 knots with gusts over 20 knots and waves from 1 to 3 feet. Marine information is provided as general guidance. Boaters should always stay tuned to the latest forecasts and advisories from the National Weather Service.
