An arctic cold front will usher in bitterly cold temperatures on Wednesday along with the chance for a few snow showers or even a snow squall.  Winds will pick up out of the west with gusts up to 35 mph.  This will help drive wind chills values well below zero with many areas expected to bottom out 20 to 30 below zero Wednesday night into early Thursday.  Wind chills will remain below zero through the day Thursday.
