77° on Nov. 11, 2020, the hottest reading for this week of the year since 1895. Next is 76° in 1928.
St. Paris’s center stands about 1,220 ft above sea level. Within three miles the land runs from 1,110 ft to 1,240 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Clinton and Cataract Groups, Undivided (dolostone, limestone, shale), from the Silurian, 422 to 445 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 47×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Silurian, 422 to 445 million years old. About 11 mi of the line.
Shale, dolostone, limestone. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Dolostone. Age: Silurian, 425 to 445 million years old. About 5 mi of the line.
Dolostone, limestone, shale. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.

A raindrop that lands in St. Paris reaches the Gulf of America by way of Nettle Creek, the Mad, the Great Miami, the Ohio and the Mississippi: about 1,580 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of St. Paris; river miles along the main stem, rounded.
St. Paris has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 19° in January. About 44 inches of rain fall in a normal year.
On November 14 St. Paris normally reaches 52° and falls to 33°. The record high is 75°, in 1909; the record low 5°, in 2019. The most rain on this date, 1.30 in, fell in 1972.
Normals 1991–2020 and records since 1895 at Urbana Wrf, 10 miles east-southeast, 200 ft lower. NOAA, through RCC-ACIS.
