Day: the 24 hours ending at 16:00 UTC (11 a.m. EST, 10 a.m. CST) on January 21, 2010, so morning observations count toward the day they end. Ice is the thickness of ice on surfaces as measured by the observer; reports of a trace (0.00″) are left out.

Spotter reports: National Weather Service Local Storm Reports (LSRs): measurements sent to NWS offices by trained storm spotters, CoCoRaHS and co-op observers, NWS staff, the public and others, archived by the Iowa Environmental Mesonet (Iowa State University). Reports are what each observer measured at one spot, often a storm total so far, and the NWS doesn't quality-check every one. Exact repeats count once.
