An upper pacific trough brought moisture into mainly the southeast zones. An arctic high pressure over the Canadian Prairies brought northeast winds that combined with an unseasonably cold airmass to bring dangerous wind chills over areas mainly north of the Missouri River. Wind chills reached -30F in some places. |
