This will set up a warm front our south like last Sunday. However unlike last Sunday the warm front sets up much further south with cold air more important for a longer period of time. This creates the possibility of a solid band of accumulating snow before it goes to ice and then to rain. We will see temperatures essentially rise from the low teens and single digits Friday morning to the 50s by Sunday morning. Something has to give with such a temperature change and it could be with a front end accumulating snow.
