Snow Possible This Week In MD: See Latest Timeline, Forecast

Maryland has two chances for light snow this week. This could be the season's first snowfall in much of the Baltimore-Washington area.

A winter storm is expected to roll into Maryland from Monday night into Tuesday morning. With a high near 41 degrees on Tuesday, the Old Line State is on the fringe of the wintry and rainy sides of the storm.

A dusting of snow is possible in central Maryland, but the main concerns are ice and heavy rain. Northern and western Maryland are anticipating the most ice.

Western Maryland could see 1 to 3 inches of snow, but the Interstate 95 corridor is expecting a trace to 1 inch. Areas east of I-95 may not see any snow unless the storm proves stronger than anticipated. If the system strengthens, even southern Maryland could get a trace of snow.

"The rain versus snow line is expected to come close to the Interstate 95 corridor between Monday night and Tuesday," AccuWeather Meteorologist Brandon Buckingham said. "A slight shift in the storm track farther offshore could help to pull in cold enough air for snow to occur in places like Philadelphia, New York City and Boston."

Winter precipitation should start around 5 a.m. and finish by 1 p.m. Tuesday.

Northern Harford and Baltimore counties will be under a winter weather advisory from Monday night until Tuesday morning.

"High pressure will return today. The next storm system will move across the region early Tuesday morning, and this will bring a wintry mix to much of the region," the National Weather Service wrote Monday in a forecast discussion. "The Tuesday morning commute could be impacted."

The NWS noted that "another disturbance may move through the region later in the week." Friday night has a possibility of snow, with a low of around 25 degrees. The chance of precipitation is 40%.
