CHICAGO (AP) - A persistent weather pattern driving bitterly cold air south out of the Arctic will cause temperatures from Minnesota to Kentucky to plummet Monday, turning this winter into one of the coldest on record in some areas.
For about 2½ days, actual temperatures will range from the teens to below zero, and the wind chills will be even colder, minus 43 in Minneapolis, minus 23 in Milwaukee and Chicago, minus 14 in Kansas City, Mo., and minus 3 in Louisville.
In fact, the National Weather Service says most of the Midwest will feel far colder than Monday's expected high in the nation's northernmost city, Barrow, Alaska -- minus 4.
National Weather Service Meteorologist Scott Blair stops short of calling the latest round of cold part of the polar vortex, which are winds that circulate around the North Pole.
He says "There's really nothing abnormal about the air that's coming into the area," adding, that "it's just been a very persistent pattern" of cold air.
