Strong warm air advection took place across Iowa during the day on the 5th.  The airmass was quite cold with shallow Arctic air in place.  At the same time a weak surface front pushed southeast out of Nebraska into northern Missouri.  This was a fairly typical Alberta Clipper type weather system.  Snow began to fall heavily around mid day and lasted through the evening.  A band of heavy snow fell from northwest of Fort Dodge through Oskaloosa.  In the band, six to nearly 8 inches of snow fell in a 12 hour period.  The heaviest snow fell in Ankeny, where 7.8 inches was measured.  Around 7.5 inches fell in the Ames area.  There was little wind associated with the storm, however road conditions became quite slick.
