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.

Snow: NOAA National Operational Hydrologic Remote Sensing Center (NOHRSC), National Snowfall Analysis (version 2.1), 24-hour totals on a 0.04° grid (about 4 km). NOHRSC builds it from NWS, CoCoRaHS and other snowfall reports, radar and gauge precipitation (Stage IV) and model snow-to-liquid ratios. Rain: NOAA MRMS multi-sensor 24-hour precipitation (radar adjusted to rain gauges, about 1 km), from the Iowa Environmental Mesonet archive; it is total liquid, so it includes melted snow and sleet. Places: US Census Bureau ZIP Code Tabulation Areas (2024 Gazetteer internal points) and city centers. Each value is the estimate for the grid cell that contains the ZIP code's or city's center point, not a measurement at your house. NOAA reruns recent analyses as late reports arrive, so the last few days can change slightly. These are our own summaries of public NOAA data; NOAA has not reviewed them.
