Estimated, not measured. No rain gauge has ever stood inside 45862 (Mendon), so every figure here is worked out from the gauges around it - the nearest ones weighted most. Treat them as close estimates rather than readings.

48,862 days of records, 1893-01-01 to 2026-10-29. Source: NOAA NCEI GHCN-Daily, 3,240 gauges in and around Ohio. A day is "gauged" when a gauge standing inside the boundary reported it, and the value is the mean of those gauges. Otherwise it is interpolated by inverse distance from every gauge reporting within 50 miles. Nothing is carried forward, back-filled or smoothed. Against NOAA nClimDiv county monthly precipitation over 136,848 complete county-months (checked 2026-10-31): correlation 0.9515, median absolute difference 0.217 in a month. Built 2026-10-31 from the Cracked Buckeye precipitation archive. Snow is the softer number — snowfall is measured by hand with a ruler, no agency publishes a gridded county snowfall series, and blowing snow defeats every observer.
