Another cold trough moved into the state for more sub-zero temperatures and wind chills. Warning criteria wind chill values (-40F) were more common with this surge than the previous one as a 1044 mb surface high moved southward from the Canadian Prairies. The cold air was followed by strong westerly flow, which brought another round of strong surface winds to the plains and portions of southwest MT.
