For areas receiving snow, it will mostly be heavy and wet, making for dangerous driving conditions.

On Sunday, the western half of Texas will be looking at temperatures 20 to 30 degrees below normal. A lot of that cold air will stay in place through Monday.Wind will also be a factor, not only helping to blow the snow around reducing visibility, but also allowing for low wind chills.Amarillo, Midland, and Odessa, Texas, are all expecting winds of 10 to 15 mph, which will bring wind chills down to around 20 degrees.Areas of southcentral Texas, including Austin, likely will see some of that rain freeze overnight Sunday when temperatures may dip below freezing.

Colder temperatures arrive today, and snow will start this afternoon in the northern mountains, spreading southward and eastward by the evening. #nmwx pic.twitter.com/J7kUnGo3kP
