Harford County residents are bracing for what could be the season's biggest snowfall Thursday, with some forecasts calling for as much as 8 to 12 inches before the storm moves out.
Rain has pelted the county most of Wednesday and is expected to continue throughout the evening, heavy at times.
But the National Weather Service and other forecasts for the area expect temperatures to drop after midnight, when the rain is expected to change to sleet and then to all snow by 4 a.m.
There could be from 1 to 3 inches of snow and sleet accumulation overnight, with an additional 4 to 8 inches of snow possible during the day Thursday, according to the NWS forecast for Bel Air.
Harford and the rest of the region are under a Winter Storm Warning from 10 p.m. Wednesday to 7 p.m. Friday.
Harford County government plans to send its road crews out to begin plowing at 2 a.m. Thursday, spokesperson Cindy Mumby said.
"We expect all 138 vehicles out on the road," she said.
With salt already spread over the roads following Tuesday's overnight ice storm, Mumby said they will reassess the salting situation, as the weather develops overnight.
By 2 a.m., however, "we expect at that time, just based on the weather reports, that we will need to be plowing," she said.
Harford County Public Schools opened two hours late Wednesday morning because of icy roads, but all after school and evening activities are going on as scheduled.
Because of the heavy snow in the forecast, Patterson Mill High School's production of "Hello, Dolly!" slated for Friday, Saturday and Sunday is being postponed until Saturday, March 14 and Sunday, March 15, the school announced Wednesday.
