Wednesday night, the heaviest snow fell between 9 and 10 p.m. in Baltimore, which saw about 0.5 inches, said Ray Martin, a meteorologist with the National Weather Service. Areas of Garrett County, he said, reported the most accumulation: 2.5 inches.
The total at Baltimore/Washington International Thurgood Marshall Airport was not available Wednesday night, but 1 inch was reported west and south of Baltimore, Martin said.
He said it was a "completely separate system" from the winter storm forecast to begin Friday night and dump 2 feet on the region.
In Baltimore, crews transported one person to the hospital after a crash on southbound Interstate 83 near Maryland Avenue. The victim's condition was not immediately available and it was not immediately clear if snow was a factor.
Meanwhile, a salt truck was dispatched to Northeast Baltimore for another water main break, according to the Office of Emergency Management. Near Lake and Mannasota avenues, the water was freezing over the street. A water main break was also reported near 300 Frederick Road in Catonsville.
