"Losing ground on Ohio" compares trends, not levels: a county can be losing ground while its own number improves, if the rest of the state improved faster over the same years.

How Clinton County began
Clinton County was formed by the Ohio General Assembly on February 19, 1810 (effective March 1, 1810), from parts of Highland and Warren counties, and named for George Clinton, then Vice President of the United States and formerly governor of New York. Its seat, first platted in 1810 as "Clinton" and renamed Wilmington in 1811, sits at the center of a county whose land had been Shawnee, Miami, and Delaware hunting and travel country before the 1795 Treaty of Greenville opened it to survey and settlement. Quaker settlers from Virginia, Pennsylvania, and the Carolinas gave the county a strong Underground Railroad tradition in the decades before the Civil War and, in 1870, founded Wilmington College. In the twentieth century the county's economy turned twice on the same patch of ground outside Wilmington: a Cold War Air Force base that closed in 1971, and the civilian air-cargo hub — first Airborne Express, later DHL's Wilmington Air Park — that grew on the same site and then collapsed when DHL pulled out in 2008-2009.
The county seat was first platted in 1810 on land donated by David Faulkner and Joseph Doan near the center of the new county, and was itself first named Clinton, matching the county. In 1811 the town's name was changed to Wilmington. It was incorporated as a village in 1828. By 1833 Wilmington held a brick courthouse, a jail, 14 stores, two taverns, two groceries, four churches, and about 100 houses. The Society of Friends (Quakers) settled the area in large numbers from Virginia, Pennsylvania, and the Carolinas, and in 1870 Quakers founded Wilmington College; the city still counts more than a dozen Quaker meeting houses. The present Clinton County Courthouse, in the Beaux-Arts style, was dedicated October 22, 1919, at a cost of $370,000.

Almost every day here is a measurement: 92% of them come from a rain gauge standing inside Clinton County itself.
48,876 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.

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.
