Heavy rain turned to heavy snowfall across York County on Sunday evening, prompting emergency management officials to urge anyone who does not need to drive this morning to stay off the roads.
"Stay home," said Cotton Howell, York County's director of emergency management. "Take advantage of the weather."
Schools in York, Chester and Lancaster counties are closed today. Classes at Winthrop University also are canceled.
The National Weather Service issued a winter storm warning for York, Chester and Lancaster counties Sunday, forecasting 4 to 6 inches of snow for the region.
Overnight temperatures were expected into the mid- to upper-20s, creating so-called "black ice" and hazardous driving conditions for motorists.
Snowfall was expected to stop around sunrise, said Neil Dixon, meteorologist for the National Weather Service.
Today's forecast calls for sunny skies and chilly temperatures reaching the mid- to upper-30s, Dixon said.
The slight warming should melt some snow, which will turn to ice Monday night as temperatures drop into the mid teens -- once again creating hazardous road conditions into Tuesday morning.
Tuesday's high will be in the mid-40s, Dixon said.
City and county crews began preparing area roads as soon as heavy rains stopped late Sunday afternoon and switched to snow, said Howell.
Public works trucks spread brine -- a salt solution that melts ice -- on roads late Sunday to help prevent black ice as temperatures dropped. Crews will continue to assess and address road conditions throughout the morning, Howell said.
Dozens of minor traffic accidents were reported late Sunday as heavy snowfall fell throughout the region and accumulated on roads.
Utility officials said they are not expecting power outages from snowfall. Scattered power outages occurred in York County on Sunday from heavy winds earlier in the day.
