Reports of sleet across region as cold weather returns

A cold rain mixed with sleet brought a rude awakening to many Tuesday morning after three straight days in the 60s in Baltimore.

Reports of the wintry precipitation cropped up across the state, according to reports on Twitter.

WBAL-TV forecasters Tom Tasselmeyer and Ava Marie reported a wintry mix on TV Hill in Woodberry about 10 a.m., while Foot's Forecast saw some in Towson. Others tweeted about it in Scaggsville, Glen Burnie and Columbia.

A cold front passed through the region late Monday night, with temperatures still in the lower 60s shortly before midnight at BWI Marshall Airport but dropping to a low of 42 degrees early Tuesday. About 0.44 inches of precipitation fell at the airport from midnight through 11 a.m. Tuesday, though the National Weather Service's Baltimore/Washington forecast office's hourly observations at the airport lists it all as rain.

Sleet is not to be confused with hail, a phenomenon that occurs in tall thunderstorm clouds. Sleet occurs when normal frozen precipitation falls from clouds, melting as it passes through warmer air lower in the atmosphere before refreezing as it meets colder air again closer to the ground.

Highs are expected to be about 20 degrees cooler Tuesday than they were Monday, perhaps climbing to about 50 degrees after the clouds clear out in the afternoon.
