An Alberta Clipper system came roaring through the flow, bringing with it very strong winds, bitter arctic temperatures, and snowfall across large portions of Iowa. Fortunately, the strongest winds were not concurrent with the greatest snowfall. As the surface low pressure system came ripping through the Dakotas during the afternoon of the 27th, isentropic lift/warm air advection into the system increased over Iowa, especially northern and northeast Iowa. The surface low approached and traversed across Iowa during the overnight hours of the 27th into the 28th, leaving northern and northeast Iowa in the warm air advection wing. While winds did reach into the mid to upper 20s mph sustained at times, the main concern was snowfall. When all said and done, roughly 4 to 8 inches of snow fell across the warning area over a roughly 12 hour period with periods of blowing snow mixed in. Two of the strongest wind gusts recorded with the storm were 58 kts observed on the 28th at both the Iowa DOT Rockwell City RWIS site at 3:20 CST and at the Des Moines Airport ASOS at 05:22 CST.
