Freezing rain overnight left a glaze of ice across the Baltimore region Tuesday morning, along with several more inches of snow across northern Maryland, and wintry precipitation was lingering into midday.

Until then, the National Weather Service warned that as much as a few tenths of an inch of ice could quickly accumulate Tuesday morning around Baltimore, especially north of the city. A winter weather advisory is in effect for Baltimore and southern Howard, Baltimore and Harford counties until 1 p.m.


In northern portions of the region, including Carroll, northwestern Howard, northern Baltimore and northwestern Harford counties were under a winter storm warning until 1 p.m.

Another several inches of snow were expected by Tuesday afternoon in northern Maryland, with 3 inches to 7 inches of total accumulation expected by Tuesday morning, including snowfall from Sunday night and Monday. And ice accumulations could reach a quarter of an inch.

As much as 9 inches of total snowfall is possible in some spots in Baltimore and Harford counties along the Pennsylvania line, the National Weather Service said.

Temperatures remained in the lower 30s by midday Tuesday, and the mid-30s in areas close to the Chesapeake Bay, the weather service said. It advised anyone venturing out to watch for ice.

A cold rain is forecast through the afternoon and evening. Temperatures around Baltimore are forecast to only reach the mid-30s Tuesday.

The weather service reported as much as 6.7 inches of snow in Bel Air, 4.6 inches in Manchester and 3.5 inches in Brooklandville as of Tuesday morning.

With the roads slick, Maryland State Police said they responded to 226 crashes from midnight Monday to 5 a.m. Tuesday.

Baltimore Gas and Electric Co. said about 10,000 customers were without power as of noon, and about 12,000 outages had been restored.

“While BGE continues working to restore service as safely and as quickly as possible, we remind our customers that there could be additional outages throughout the day as trees and tree limbs weakened by the weather system continue to impact electric service,” Rodney Oddoye, BGE’s chief customer officer, said in a statement.

With cold air blowing in as the system departs, another period of flurries is possible late Tuesday night, forecasters said.

Sunshine is forecast to return Wednesday, with highs in the lower 40s. Then, mild conditions are forecast by Thursday and Friday, when highs are expected to reach the lower 50s.
