Winter Storm Coats Southern Plains in Snow

Winter Storm Fern is dumping heavy snow across Texas, Oklahoma and Arkansas, transforming communities that rarely see winter weather like this. Arctic air crashed into the South overnight, dropping temperatures 20 to 30 degrees below normal and turning freezing rain into several inches of snow. Some areas are measuring 4 to 8 inches of snow — more than they'd typically see in an entire year. The storm is expected to continue bringing dangerous conditions through the weekend.
