MD Weather: Winter Weather Advisory Issued For Parts Of Maryland

MARYLAND — As Tuesday's rainfall transitions into snow overnight, slippery roads are possible Wednesday, according to the National Weather Service. The agency issued a winter weather advisory for several parts of north-central Maryland effective Wednesday morning.

About 1 to 2 inches of snow are expected in six counties, which are under a winter weather advisory from 2 to 8 a.m. Wednesday, Dec. 11. In elevations above 1,000 feet, there could be three inches of snow, according to the advisory.

The winter weather advisory applies to the following counties:

• Baltimore
• Carroll
• Frederick
• Harford
• Howard
• Montgomery

Those under the winter weather advisory should be extra careful when walking outside Wednesday morning, since sidewalks, steps and driveways may be slippery, officials advise.

Drivers should reduce their speeds because of potentially hazardous conditions.

The rain-snow mix is expected to arrive after midnight.

"Rain will likely change to snow and may accumulate several inches tonight before ending," the National Weather Service said in a hazardous weather outlook Tuesday morning. "If the threat materializes, it may cause travel disruptions."

Temperatures will hover in the 50s Tuesday and may even reach 60 degrees before plunging toward freezing overnight.

Forecasters are calling for rain before 1 a.m., rain and snow from 1 to 4 a.m., then snow from 4 to 10 a.m. Wednesday. Less than one inch of new snow accumulation is possible, according to the National Weather Service.

By Wednesday morning, much of Maryland may have a coating of snow on the ground, forecasters say.

Snow accumulations on roads will be "substantially less, if there are any at all, than what accumulates on grass and car-tops," the National Weather Service forecasters said in a forecast discussion. "That said, there is still a significant risk of an advisory-level event north and west of I-95, [on] either side of a line from Westminster, MD, southwest to Staunton [Virginia]."

Forecasters were calling for less than an inch of snow in Baltimore and 1 inch in Frederick and Hagerstown, in their predictions issued Tuesday morning. They revised the forecast Tuesday afternoon to indicate no accumulation was expected anywhere in Maryland, but there was the possibility on the high end of the spectrum that most of the state could get 1 or 2 inches, with Camp David and Westminster seeing 3 inches of snow.

Any precipitation is expected to move out Wednesday morning, with sunshine returning and temperatures rising into the low 40s; as a result, any snow will melt. Weather officials said a wintry mix is also possible Friday, mainly near and west of the Blue Ridge.

The hazardous weather outlook applies to the following areas in Maryland:

• Allegany County
• Baltimore City
• Baltimore County
• Carroll County
• Frederick County
• Harford County
• Howard County
• Montgomery County
• Washington County
