Yet another Alberta Clipper storm chugged into the upper Midwest during the early morning hours of 12/20, this time tracking from the high Plains into Minnesota and Wisconsin.  The system brought periods of heavy snow to the area.  The snow began in east central and northeast Iowa around sunrise, and then spread south and east through the morning hours.  The heaviest amounts of 3 to 5 inches fell along and north of a line from Sigourney Iowa, to the Quad Cities, to Sterling/Rock Falls.  1 to 3 inch amounts were common to the south and east.  The snow once again kept area law enforcement officials busy, with many accidents across the area.  The snow had tapered to flurries by midnight.  As low pressure headed off to the northeast, a northwest wind picked up to 20 to 30 miles an hour during the overnight, and produced bitterly cold wind chills of 30 to 45 below zero, as actual temperatures dropped into the single digits.  Blowing and drifting snow continued into the day on 12/21.
