Some regions in Maryland could see ice accumulations of up to two-tenths of an inch overnight, the National Weather Service said.

The weather service wrote Monday night that freezing rain is expected for “portions of western Maryland and eastern West Virginia" as well as north-central and northeastern Maryland, “especially near the Mason-Dixon line.”


A winter weather advisory was in effect until midnight for northern Baltimore, northwestern Harford County, central and eastern Allegany County and Carroll County.

Temperatures were expected to be in the lower to mid-30s through daybreak.

It comes after some of the state received a dusting of snow Monday.

A winter weather advisory expired at 10 a.m. Monday after as much as 2 inches of snow fell in parts of the Baltimore region, and precipitation was turning to light rain and sleet as temperatures warmed.

The weather service reported as much as 2 inches of snowfall in Carroll County on Monday, and more than an inch in much of Howard, Baltimore and Harford counties. Just a tenth of an inch of snow had fallen at Baltimore-Washington International Thurgood Marshall Airport by 7:25 a.m. Monday, the first measurable snowfall this season at the region’s point of record.

The weather caused several Baltimore-area school systems to close Monday, including Baltimore, Harford, Carroll and Howard counties.

For Carroll, northern Baltimore and northwest Harford counties, the weather service predicted mixed precipitation with total snow accumulations of 1 to 3 inches and ice accumulations of around one-tenth of an inch through 1 p.m.
