A broad southwest flow aloft was in place over Iowa.  Low pressure developed over the southwest U.S. over the weekend of the 13th and 14th.  A considerable amount of warm air was drawn north over the top of colder air at the surface.  The cold front that usher in the cooler air was located well to the south of the state, however a large area of freezing drizzle and some freezing rain developed during the night of the 13th ahead of the main system.  Low pressure developed along the cold frontal boundary and tracked northeast through the Ohio River Valley.  Freezing precipitation changed to snow across Iowa as the colder air deepened.  Snow became widespread by the late afternoon and evening hours as Iowa fell under the influence of the warm conveyor belt precipitation in the deformation zone.  Much of the state received 3 to 5 inches of snow with some areas of the west central into the north central counties picking up 6 or more.  The heaviest snow fell in Greene County at Dana, with 8 inches.  Most of the totals in the heavier snow area were in the 6 to 7 inch range.  There was some banding of the snow, which lead to the scattering of higher totals.  In the Story City area of Story County, a heavier band of snow produced anywhere from 6.7 to 7.2 inches of snow across the city.
