How Madison County began
Madison County was formed by the Ohio General Assembly on March 1, 1810, one of five counties (with Fayette, Pickaway, Guernsey and Clinton) organized that same year, and named for President James Madison. Its seat, London, was laid out on donated ground in 1810-11 as a compromise site near the county's center. The county's rolling, once-treeless prairie land at the edge of the Darby Plains had been Shawnee, Wyandot and Mingo hunting ground before the Treaty of Greenville of 1795 opened it to settlement, and the county's first Euro-American settler, Jonathan Alder, arrived not as a pioneer from the East but as a former Shawnee-Mingo captive returning to white life after about thirteen years among the Mingo on the Mad River and the Shawnee at Blue Jacket's and other towns. Flat, fertile and largely free of the forest cover that slowed clearing elsewhere in Ohio, Madison County grew into cattle and sheep country by the 1850s and then into some of the state's best-known horse-breeding and grain farmland, a character it still carries as Interstates 70 and 71 cross it on their way into Columbus.
London was chosen and platted as county seat in 1810-11 on land donated for the purpose near the geographic center of the new county, a common arrangement for Ohio county seats of the period intended to make the courthouse roughly equally reachable from all townships. The present Madison County Courthouse, a Second Empire-style building on the Public Square designed by architect George H. Maetzel, was constructed in 1892 (an earlier courthouse having served the county from its 1810s organization) and was listed on the National Register of Historic Places on March 14, 1973; its Lady Justice statue was knocked down by the tornado of the April 1974 Super Outbreak.

45,992 days of records, 1900-09-01 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.
