As expected, the frigid air has arrived in the Southeast, and near-record setting temperatures were experienced across a lot of the area this morning. The map from CRONOS from the North Carolina State Climatology Office at 8 am below shows the extent of the cold air.
Today the maximum high temperature in many areas will stay below freezing and is expected to set new daily records across the area. On Friday the cold will continue and more records of minimum and maximum temperature are expected to be set at many stations before a warming trend sets in. After a winter storm affects far northern parts of the region on Friday into Saturday, temperatures are expected to warm up and we may see temperatures in the 60s by Sunday.
