The Charlotte region is under a dense fog advisory until 10 a.m. Tuesday.
Drivers should slow down, use their headlights and leave plenty of distance ahead of them.
Once the advisory lifts, the day should remain mostly cloudy before rain moves into the area by early Wednesday.
The chance of rain will increase from 50 percent early Wednesday to 90 percent the rest of the day, according to the National Weather Service in Greer, S.C.
The rain should clear out by Thursday, which is expected to remain cloudy.
All sunshine is forecast for Friday. Saturday and Sunday are expected to be mostly sunny.
A chance of showers could return Monday, although at 30 percent, the chance right now is slight.
Temperatures, meanwhile, will continue to bounce around this week.
At 56, Tuesday’s high should be a few degrees above normal.
The high is then expected to shoot up to 68 Wednesday before highs drops right back down to 53 Thursday and a below-normal 48 Friday.
Highs should then gradually climb again, to 50 Saturday, 55 Sunday and 54 Monday.
