The National Weather Service has issued a winter storm warning and a watch for the greater Baltimore region and much of the mid-Atlantic beginning Monday afternoon in advance of a storm that could bring the region’s first significant snow of the season.
The weather service predicted Sunday that the approaching storm could bring from 4 to 17 inches of heavy snow to various parts of Maryland.
Carroll, Frederick, northern Baltimore, northwest Harford and Howard are under a winter storm warning with possible accumulations of 6-12 inches, the weather service said. Other parts of central Maryland are under a winter storm watch with at least 5 inches of snow forecast.
The winter storm watch will be in effect from 7 p.m. Monday to Tuesday afternoon.
“This is the first notable snowstorm for the central part of the Mid-Atlantic,” said Bryan Jackson, a meteorologist for the National Weather Service.
Officials said the “major coastal storm” was expected to form as a low pressure system off the Caroline coast Monday, then move northeast toward the Mid-Atlantic by Tuesday. Heavy precipitation is expected along the western edge of the system, bringing substantial snow accumulations.
Precipitation is expected to begin around 5 p.m. Monday, then turn to mainly snow after 8 p.m. with low temperatures around 31. Winds could gust as high as 21 mph and snow accumulation of 3 to 7 inches is possible, the weather service said.
On Tuesday, more snow is expected in the morning into the early afternoon, then turn to snow showers after 2 p.m. with temperatures near 37 degrees. More snow showers could come Tuesday night and early Wednesday, the weather service said.
The storm comes less than a week after the region was basking in 71-degree weather and the scent of blooming flowers — much of Maryland was considered to be in a “snow hole,” as previous storms have tracked to the north and south.
The Baltimore area has only seen 0.7 inches all season at BWI Marshall Airport, which ties a record for the least amount of snow, set nearly seven decades ago.
