Typically, when a polar vortex system sets up over the Great Lakes and southern Canada, we have dry weather around Kansas with lake effect snows in the upper Midwest. And it can take a few days to a week for these large systems to break down and move away. This one won't be around for much longer. I think by Wednesday, it will be weakening and heading east. Much of the country should be climbing out of the deep freeze as the week continues.
Almost half way through winter, here is how we stand on snowfall for the season. Most areas are near normal on snow, except in the northwest, where several places are 5-10 inches below average. One good winter storm can wipe that out.
