The coldest weather of the season is moving into the mid-south. By Friday morning look for lows in the low 20s in north Texas, upper teens in south Arkansas, low to mid teens in central Arkansas, and single digits in the northern part of the state. I would not be surprised to see one of the traditionally cold valley locations reach zero. No snow....continued very dry.
