CHICAGO (AP) — A persistent weather pattern driving bitterly cold air south out of the Arctic will cause temperatures 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 with 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.
