Maryland Weather Meteorology, astronomy and climate conditions in the Baltimore region

Light snow forecast Friday, possibly knocking winter to No. 2 on least-snowy list

Hold up, spring: A light snow is possible Friday, with frigid temperatures to follow.

A dusting of snow could coat grassy surfaces across the Baltimore region Friday as a burst of cold interrupts what has been an early start to spring.

If any measurable snow falls at the region's point of record, BWI Marshall Airport, it would knock this winter out of a tie for the region's least snowy on record.

A storm known as an Alberta clipper, a fast-moving and relatively impotent system from Canada, is forecast to sweep through between daybreak and noon, said Dan Hofmann, a National Weather Service meteorologist.

It could bring some quick snow squalls, but given recent warmth and above-freezing temperatures expected Friday morning, no significant accumulation is expected.

"It really just looks like the worst-case scenario is there could be maybe a couple tenths of an inch on the grass or elevated surfaces," Hofmann said.

So far this winter, 0.7 inches of snow has fallen at BWI, tying it with the winter of 1949-1950 as Baltimore's least snowy on record.

Measurable snow has not fallen there since Jan. 7, though traces have been reported on nine occasions.

The wintry weather comes after a February that was Baltimore's warmest on record, as BWI temperatures averaged nearly 81/2 degrees above normal. Then meteorological spring began Wednesday with a high of 75 degrees, about 25 degrees above normal.

Now a spell of below-normal temperatures is here. Highs are forecast in the lower 40s Friday through Sunday, and lows are expected to fall into the lower 20s early Saturday and Sunday mornings.

Temperatures are forecast to rebound to the 60s next week.
