Ian,
Here in the Dallas -Ft. Worth area ANY hint of snow or ice causes and uproar. Mostly it is people who have never had to drive in real winter weather that cause the problem along with the fact our cities are not prepared to deal with ice and snow on the roads. So, yes. With the temps never getting above freezing the next several days a lot of places will close and those with any sense at all will stay at home until the ice clears.
