11° on Nov. 14, 1986, the coldest reading for this week of the year since 1934. Next is 11° in 2019.
Thornport’s center stands about 900 ft above sea level. Within three miles the land runs from 870 ft to 1,140 ft, a difference of 270 ft: rolling country. The highest named summit within 15 miles is Coffman Knob, about 1,270 ft, 8 miles north-northeast.
Under the town center the state geologic map shows Maxville Limestone; Rushville, Logan, and Cuyhoga Formations, Undivided (shale, siltstone, sandstone), from the Devonian to Carboniferous, 324 to 422 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 51×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 23 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 324 to 359 million years old. About 0.8 mi of the line.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 0.4 mi of the line.

A raindrop that lands in Thornport reaches the Gulf of America by way of the South Fork Licking, the Licking, the Muskingum, the Ohio and the Mississippi: about 1,900 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 Thornport; river miles along the main stem, rounded.
Thornport has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 18° in January. A normal year brings about 15 inches of snow; with the rain, that comes to about 43 inches of water.
On November 14 Thornport normally reaches 52° and falls to 31°. The record high is 72°, in 1971; the record low 11°, in 1986. The most rain on this date, 1.40 in, fell in 1949.
Normals 1991–2020 and records since 1934 at Newark Water Works, 12 miles north. NOAA, through RCC-ACIS.
