An amplified upper level trough, cut off at times, swept through Kansas, Missouri and Illinois. The attendant surface low also swept through Kansas and Missouri on a similar path, well south of Iowa. The surface low was tightly wound, slowly deepening from about 998mb to 994mb as it traveled south of the state. Precipitation associated with the warm advection wing and wrap around areas initially saw rainfall during the evening and overnight hours of the 24th into the 25th before transitioning over to snow as colder air filtered in. An extremely tight precipitation/snowfall gradient set up roughly along Interstate 80 and south as precipitation processes battled a cold, dry air intrusion from the north. As a result, gradients in the snowfall were so tight that some areas that received 6 to 8 inches of snowfall or more were only a dozen or so miles south of areas that received as little as an inch or less.  Throughout the day, the heaviest banded snowfall remained situated over southern Iowa, resulting in numerous reported snowfall amounts in excess of a foot and as high as 16 to 17 inches. While the snow tended to be on the heavy and wet side, strong winds on the backside of the low, gusting in excess of 40 mph regularly, helped degrade conditions and keep visibilities well below a quarter to half mile throughout much of the mid to late morning and afternoon.
As one might imagine, numerous travel issues were reported in the heaviest hit areas, including dozens of vehicles in ditches along Interstate 35 south of Des Moines, and temporary closures of the interstate due to disabled vehicles on the roadway. Fortunately, reported power issues were generally intermittent, and tree damage was not substantial.
