Maryland weather: Little or no additional snow accumulation expected Thursday

Several inches of snow fell overnight in the Baltimore area, causing some delays and closings, and forecasters anticipate more wintry weather could be on the horizon.

A winter weather advisory will be in effect from 4 p.m. Thursday afternoon until 7 a.m. Friday morning in northern Baltimore County, northwest Montgomery County and northwest Harford County, plus Carroll, Frederick and Washington counties, according to the National Weather Service.


Thursday, forecasters say there’s a 20% chance of snow, rain and freezing rain, but there’s expected to be little to no extra snow accumulation.

There’s a 20% chance of snow Thursday evening, according to the National Weather Service.


The snow started to fall around 9 p.m. Wednesday after about two hours of wintry mix of sleet and freezing rain in the area.

Baltimore City’s Pimlico neighborhood had recorded 4.9 inches of snow by 6:30 a.m., and Catonsville in Baltimore County had recorded 3.8 inches as of about 8 a.m. Towson and Perry Hall had around 5 inches.

BWI Marshall Airport in Anne Arundel County had 2.6 inches at 7 a.m. Columbia in Howard County had 3.7 inches, and Forest Hill in Harford County had 4 inches.

The Maryland State Police said that between 4 p.m. Wednesday and 10 a.m. Thursday, they responded to 102 crashes, 74 disabled or unattended vehicles and answered 758 calls for service.

Temperatures aren’t likely to rise above the 30s until at least the middle of next week, the weather service said.

“With cold air so locked into place, there will be a couple of shots at some more wintry precipitation through Tuesday,” forecasters said.

Most of Friday will be dry, forecasters say, and high temperatures will be in the upper 20s. But Saturday into Saturday night, there’s likely to be a mixture of sleet and freezing rain. There could be “substantial accumulations of freezing rain,” forecasters wrote. Sunday, there’s a 60% chance of freezing rain.


The next chance for wintry weather will be Monday night into Tuesday, after low pressure builds on the Gulf Coast before heading up to the Appalachians. It’s still early, but forecasters expect this to be freezing rain and sleet.

This week’s snowfall is the third substantial winter storm in the Baltimore area this year. A late January storm set a record at BWI Thurgood Marshall Airport, bringing the most snow for any Jan. 31 on record — 3.8 inches.

At least one coronavirus vaccination site in the area has closed due to inclement weather. The Harford County Health Department shut the Patterson Mill site Thursday and Friday and asked those with appointments to come in earlier, according to a tweet from the department.

The Anne Arundel County Department of Health announced that its vaccine clinics would be operating as scheduled Thursday.

The Baltimore City Department of Transportation said in a news release that its snow team deployed at 4 p.m. Wednesday and pretreated city gateways and primary roadways with salt brine in preparation for the storm.

“I encourage all residents to take this storm seriously by staying home if at all possible, and taking all necessary precautions if you absolutely must travel,” Mayor Brandon Scott said in a news release.


Baltimore City issued a winter shelter declaration, which will remain in effect until 9 a.m. on Sunday. Residents in need of shelter should call 443-984-9540 or dial 211.
