Update: The Baltimore region could get as much as 10 inches of snow, according to new forecast models.

Baltimore on Friday braced for its biggest winter storm in recent years, with officials saying the city could face nearly a foot of snow next week as temperatures drop into the 20s.

Meteorologist Connor Belak of the National Weather Service said this could be “the most impactful winter storm in a couple of years” to hit the Baltimore area, coming between late Sunday night and early Monday morning. The agency predicts 4 to 8 inches of snowfall, with 10 inches the worst-case scenario. Belak said there will be better a forecast Saturday.

Joey Henderson, director of the Baltimore Office of Emergency Management, warned residents to “take this storm seriously.”

Baltimore saw 77 inches of snow in the winter of 2009 to 2010 but typically sees about 19.3 inches in the season, with most in January and February, according to NWS data.

Last year, 11.3 inches of snow fell, with 9.1 in January.

On Friday evening, drivers in the Baltimore area and surrounding counties battled snow showers and slippery road conditions as city officials urged residents to drive with caution.

NWS said 1 to 2 inches of snow fell across the region but was moderate or heavy at times, causing reduced visibility for drivers.

Baltimore Department of Transportation crews treated city streets, including overpasses, exit ramps and bridges, with salt brine ahead of Friday’s weather.

Public schools in Baltimore City and Baltimore, Howard, Carroll and Harford counties announced early closures Friday, as well as the cancellation of evening activities.

Over the weekend, temperatures could drop as low as 23 degrees, with wind gusts reaching 33 mph on Saturday.

The city is working with its partners to provide shelter from the cold and other services from Jan. 2 at 4 p.m. to Jan. 7 at 9 a.m.

Beans and Bread on South Bond Street, Franciscan Center on West 23rd Street, Manna House on East 25th Street, My Sister’s Place Women’s Center on West Franklin Street and Weinberg Housing and Resource Center on Fallsway are all warming centers. Here is a full list of warming and overnight shelters, with contact information.

The state Department of Transportation will continue treating roads Saturday.

The agency has about 250 pieces of snow equipment for plowing streets, as well as 400 more pieces under contract that could be tapped, city officials said.

Baltimore plows city streets on a tiered system, with major thoroughfares getting priority.

Mayor Brandon Scott asked residents to avoid traveling in the expected storm if they can and to check on older or disabled neighbors.
