What happened
The episode as NWS DMX wrote it up.
A low pressure system passed to the south of Iowa during the day on the 5th. The north edge of the precipitation stretched into the state in the form of the northern edge of the deformation zone. Rain fell initially, however the system became convective. The combination of the convection and the entrainment of dry air into the state led to a fairly quick changed to snow. A narrow band of heavy snow set up across Appanoose, northwest Davis, and Wapello Counties. At the heaviest point, snow fall at the rate of 3 inches per hour. In a band extending from near Centerville to Ottumwa, 6 to 7 inches of snow fall in a three to four hour period. The official snowfall total at the Ottumwa Airport was 7 inches. This was the highest official total, though a few locations picked up a bit more unofficially.
