CHARLOTTE, N.C. – You know it's cold when temperatures above freezing feel like a break from such frigid weather! Charlotte locals will be happy to know that those temperatures are expected to continue to warm. But the increase in temperatures doesn't mean that you shouldn't be careful on the roads.

Light rainfall overnight Monday into early Tuesday morning caused surfaces to freeze, leading to concern over black ice.

NBC Charlotte's Traffic Anchor Rachel Rollar reported multiple crashes during Tuesday morning's commute due to black ice.

"Drive carefully," Rollar urged.

“Watch out for black ice," First Warn Storm Team's Larry Sprinkle said. "Rain that fell could freeze over, especially on secondary roads, bridges and overpasses," Sprinkle said.

Despite road workers prepping roads in the NBC Charlotte viewing area ahead of the icy conditions, the cold temperatures and winter weather caused multiple school districts to delay class Tuesday.

Alexander, Ashe, Avery, Burke, Cabarrus, Caldwell, Catawba, Gaston were just some of the counties that delayed school Tuesday morning. For the latest information on closings, click here.

The rest of the week is expected to have lows in the 40s with a chance of showers late next week. Charlotteans should expect highs of about 53 degrees Tuesday.
