Temperatures dropped to the lower 20s early Wednesday morning, tying a record low a day after a dusting of snow was reported across the Baltimore region. Another record low is possible Thursday morning.

Baltimore-Washington International Thurgood Marshall Airport hit 22 degrees early Wednesday, matching a record low for Nov. 13 set in 1911.

On Tuesday, a trace of snow was reported at BWI, the region’s point of record, along with 0.08 inches of rain.

Precipitation fell along a strong cold front moving across the eastern United States, producing a mix of rain and snow from the southern Appalachians into New England.

In the Baltimore region, temperatures fell quickly, but not quickly enough to support much snowfall. Temperatures fell from 60 degrees at 3 a.m. to 40 degrees by 11 a.m. at BWI, and remained around there throughout the day.

Precipitation can fall as snow flurries even if air temperatures are above freezing close to the ground because air aloft is colder. The relative warmth close to the ground could just prevent snowfall from sticking.

Heavier snow was reported in Western Maryland, with 3 inches reported in Frostburg by 8 p.m. Tuesday.

By early Wednesday morning, skies cleared amid frigid air. Wind chills are forecast to remain below freezing throughout the day, with a 10 mph northwest wind and temperatures not expected to rise out of the mid-30s.

Temperatures could reach the mid- to upper teens around the region early Thursday, threatening a record low of 18 degrees set in 1986. But then highs Wednesday are forecast to climb into the upper 40s.

Mostly sunny skies and seasonably cool temperatures are forecast the rest of the week.
