A little Southern snow can be fun. Add ice to the mix, and it can turn nasty.

As much as 3 inches of snow were forecast to fall across the Lowcountry on Wednesday, on top of as much as a half inch of ice.

Roads will be dangerously slick. Any route could be treacherous, particularly where water collects or the roadway is raised over a low-lying area.

Major bridges might well be closed. Updates can be found at postandcourier.com and social media.

S.C. Highway Patrol officers could close bridges on a case-by-case basis as ice and snow falls, and decide whether to have the Department of Transportation crews work to restore major bridges one lane at a time, said DOT spokesman James Law.

Those icy conditions might persist through the Wednesday evening commute and even into Thursday morning.

"In some respects, Wednesday night and Thursday morning commutes could be worse than Wednesday morning," said meteorologist Jonathan Lamb, National Weather Service, Charleston.

Light snow is expected to persist through the day. Temperatures will barely get above freezing.

Wednesday night will be the worst blast of cold, with temperatures in the 20s and wind chills as low as 10 degrees.

Thursday, temperatures rebound into the 40s, causing some melting, but drop into the 20s again at night.
