What happened
The episode as NWS DVN wrote it up.
A foot to a foot and a half of heavy wet snow fell in several waves of heavy snow. Snow was heavy enough to cause the collapse of many roofs. Most of the roofs were those of sheds, barns, and carports but some well built flat roofed businesses were also damaged along with many area trees. Winds remained under 15 mph throughout the event and this combined with the heavy nature of the snow kept drifting to a minimum. Perhaps the greatest impact of the storm was that most cities had to re-tool their trucks for snow removal after many of them had just modified them for summer duty. The late season snow also slowed sand bagging efforts on the Mississippi River.
