Rain is expected to continue throughout most of Wednesday before turning to a wintry mix late due to plummeting temperatures, and as much as half a foot of snow could fall Thursday in Carroll County.
Wednesday's morning and evening rush hours won't see significant winter weather, according to AccuWeather meteorologist Carl Erickson, but snow accumulations overnight into Thursday could be problematic.
A "temperature crash" Wednesday night will drive temperatures into the 20s, Erickson said, causing rain to freeze and turn to snow.
Snow accumulation between 3 to 6 inches is expected and may affect the Thursday morning commute, Erickson said.
The National Weather Service has issued a winter storm watch from 7 p.m. Wednesday until 7 p.m. Thursday for most of central Maryland, including Carroll County.
Roads are expected to be snow covered with limited visibility at times Wednesday into Thursday, according to the storm watch.
Drivers are urged to stay off the roads if possible during periods of intense precipitation, according to the Maryland Emergency Management Agency.
"Once we get past Thursday, it looks like a quiet stretch of weather," Erickson said.
Temperatures are expected to be steady and allow ice and snow to melt slowly through the weekend into early next week.
