If you have to drive around today remain cautious because some side roads still have snow, slush, and ice on them.

While temperatures will once again head above freezing during the day, when the sun falls so will the temperatures back below freezing causing any moisture left to solidify.

NCDOT crews are still working the roads to get them cleared as quickly as possible.

However, they could once again become a winter wonderland if we get any snow this upcoming weekend.

Some 220 million Americans are on alert for extreme cold temperatures forecast to follow the weekend's record-breaking winter storm.

The extreme cold warnings and cold weather advisories stretch from Texas and Florida in the South to New York in the Northeast and Detroit in the Midwest.

Cold air is expected to produce another round of lake-effect snow on Tuesday for western Michigan and western New York -- an additional 8 to 16 inches of snow is possible in some areas.

Record low temperatures are possible in the South, where temperatures will feel as low as the 20s and 30s in Florida and the 20s along the Gulf Coast.

Wind chill is expected to drop into single digits on Tuesday in the Northeast, ahead of even lower temperatures later this week. Multiple days of below-zero wind chills are forecast for the Northeast from Wednesday into the weekend.
