2021-02-07 · Northwest Harford, Maryland

Wider weather episode

Low pressure in the southern stream of the jet passed by just to the south on the morning of the 7th. However, temperatures were marginal due to the lack of cold high pressure to the north. Therefore, precipitation began as rain near Interstate 95 where low-level warm air held on. However, colder air did eventually work its way in causing precipitation to change to snow. Farther west across the farther northern and western suburbs of Washington and Baltimore into north-central and western Maryland, precipitation Mountains and westward, precipitation fell mainly in the form of snow.

Snowfall accumulations ranged less than an inch near Baltimore, to 1 to 3 inches in the nearby northern and western suburbs, to 3 to 6 inches in the farther northern and western suburbs (northwest Harford, Carroll, Frederick, northern Montgomery Counties). Snowfall amounts around 1 to 3 inches occurred near and west of Interstate 81 where there was less precipitation.
