Concern For Heavy Snow In Tennessee

There is potential for snowfall rates of up to 1 inch an hour as a cold-core upper level low circles in Kentucky/Tennessee. A cold-core upper level low (ULL) system is basically a low pressure system with cold air in the center of it. That's how snow is possible in Tennessee into Mississippi, Alabama. It is not out of the question that accumulating snows may fall in the aforementioned areas. As this cold core ULL eventually moves off, our concern will shift to another threat that may involve a snow threat for Wisconsin later on in the week.

Are cold core lows rare?

They are on the more infrequent side.
