MD Weather: Updated Bomb Cyclone Snow Forecast in MD
MARYLAND — A “bomb cyclone” of heavy rain, strong winds and snow is forecast for the weekend, and the National Weather Service has increased its confidence in the likelihood of snow, sleet and freezing rain in Maryland and updated its schedule for the winter mix.
Rain will begin early Saturday in central Maryland, then mix with snow throughout the afternoon. Temperatures are about to drop throughout the day, from the 30s and 40s to the teens and 20s at 5 p.m.
In western Maryland, the snow will be more stable in the morning. In central Maryland, the snow will be more stable by noon. Strong winds on Saturday are also a concern, forecasters said.
A wind advisory takes effect from 8 a.m. Saturday to 1 a.m. Sunday, calling for winds of 20 to 35 mph with gusts of up to 55 mph and possibly 60 mph in the Baltimore-Washington area.
“Winter weather advisories have been extended eastward to include much of the I-95 corridor for Saturday morning,” the National Weather Service reported after 4:15 p.m. Friday. “Wind advisories are also in effect for much of the region. This, coupled with heavy, wet snowfall, could lead to power outages, particularly where the heaviest snow is falling.”
These Maryland jurisdictions are subject to a winter weather advisory calling for 3 to 5 inches of snow and wind gusts of 45 to 55 mph from 6 a.m. to 3 p.m. Saturday:
- Baltimore County
- Carroll County
- Frederick County
- Harford County
- Howard County
- Montgomery County
The rain will change to snow by 5 a.m. to 7 a.m., then be more steady until noon in the areas above, officials said.
In parts of Harford County and Montgomery County, forecasters say rain, snow and sleet will turn to snow after 11 a.m. and could become heavy at times in the afternoon, with a possible accumulation of 1 at 3 inches.
Roads and sidewalks can be slippery, so drivers and pedestrians should be extra careful. Visibility can be less than 0.5 miles at times and gusts can bring down branches.

Winter storm warning issued for western Maryland
Greater accumulation is forecast for western Maryland, where the National Weather Service placed Garrett and far western Allegany counties under a winter storm warning from 1 a.m. to 1 p.m. Saturday.
About 4 to 8 inches of snow could fall there, and wind gusts of 45 to 55 mph could blow Saturday afternoon overnight, according to the winter storm warning.
The rain will change to snow from 1 a.m. to 3 a.m., then ease by noon, followed by another round of flurries Saturday afternoon and evening.
Snow and blowing snow could reduce visibility to less than 0.5 miles, officials warn, saying, “Near-blizzard conditions are possible.”
Travel can be dangerous, so anyone who has to venture out should keep an extra flashlight, food and water in their vehicle, officials advise.
In north-central and western Maryland, forecasters say up to 5 inches of snow is possible.
Eastern Allegany County and Washington County are under a winter weather advisory calling for 2 to 5 inches of snow and gusts of 45 to 55 mph from 3 a.m. to 3 p.m. Saturday. The rain will change to snow from 3:00 a.m. to 5:00 a.m. in these areas and will be more regular in the morning.
