A cold front is moving into the Triangle and creeping eastward toward the coast. Temperatures are expected to drop into the 20s later today.
Scott Sharpe is a senior forecaster at the National Weather Service in Raleigh. He said a wintry mix is expected across the region sometime after lunch.
“Once temperatures do drop, they're not going to recover. So we're expecting overnight temperatures here across the Piedmont in the teens,” Sharp said. “So whatever moisture, dew, we do have on the road by late this afternoon early evening will freeze. So we're expecting some icy conditions that will last into a good part of Tuesday morning.”
Sharp says temperatures will remain below normal for the rest of the work week.
