Monday’s cold rain was expected to be replaced overnight by freezing rain early Tuesday across the Charlotte region, which is under a winter weather advisory until 11 a.m.
Forecasts show a 40 percent chance of freezing rain moving through the Charlotte area before 8 a.m., with less than an eighth of an inch accumulation. Icy patches could form in the early morning hours.
The N.C. Department of Transportation said it would mobilize contract trucks to treat interstate bridges and overpasses in Mecklenburg and Cabarrus counties early Tuesday with a brine-calcium solution, as more frozen precipitation may create hazardous conditions on elevated surfaces.
Temperatures should rise above freezing by 10 a.m. and will eventually edge up to about 41 degrees, before shooting up to 61 on Wednesday and 65 on Thursday.

A winter weather advisory is also in effect through Tuesday morning for areas north of Interstate 40 and in the mountains, with light icing possible from near Mocksville to Taylorsville. Avery County Schools in the mountains are on a two-hour delay.
The brine-calcium solution will take longer to freeze and will provide additional protection against icing. Rock salt would likely bounce off the road and provide no benefit.
Motorists are being advised to keep a safe following distance from any trucks spraying the brine solution as they will be traveling at slower speeds.

The chance for rain falls to 20 percent on Wednesday, and precipitation should clear out by Wednesday night. We’ll finally see sun again on Thursday.
