If the surface temperature is below zero, how does the air aloft stay above freezing? Wouldn't the cold air "chill" the warmer air until it was cold enough to produce snow?? Or is that just wishful thinking

Warm air is less dense, so it is possible to have warmer air override a layer of colder, more dense air. That is exactly what is going to happen later tomorrow and tomorrow night to give the ice to areas of the central Midwest.

I am 100 miles S of Chicago and they are calling for 1/2 to 3/4 inches of ice and 15 to 20 mph winds. 70 miles north they are calling for 10" of snow. Would someone up north kick on the large fans and blow this farther south!!!!
