Arctic high pressure builds in from the Midwest through Friday bringing record cold to the region. High pressure slides offshore Saturday morning with a weak low pressure quickly approaching from the southern plains. The fast moving low pushes a warm front towards us Saturday afternoon and evening. A low pressure system tracks well north of the region Sunday morning pushing a cold front through by late in day. High pressure builds in from the west Monday into Tuesday. This will result in extremely cold temperatures, dangerous wind chills, and wintry precipitation. Temperatures will slightly moderate over the weekend before again dropping on Monday.
