WISCONSIN NEWS ROUNDUP: Another "polar vortex" is in the works this week
Get ready for another "polar vortex" in Wisconsin this week. Highs are expected to be in the teens-and-20's today -- but by tomorrow, forecasters say it could be 10-degrees colder. By Wednesday, parts of northern and western Wisconsin will be back down to 20-below. The entire state could be in the deep freeze until Friday, well below normal for this time of year.
