7° on Nov. 17, 1959, the coldest reading for this week of the year since 1893. Next is 8° in 1916.
Clifford’s center stands about 660 ft above sea level. Within three miles the land runs from 640 ft to 690 ft, a difference of 50 ft: nearly flat ground. The highest named summit within 15 miles is Taylor Hill, about 1,020 ft, 12 miles southwest.
Under the town center the state geologic map shows New Albany Shale (black-shale), 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 57×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, dolostone. Age: Devonian, 359 to 422 million years old. About 13 mi of the line.
Black-shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 7 mi of the line.
Siltstone. Age: Carboniferous, 324 to 359 million years old. About 5 mi of the line.

A raindrop that lands in Clifford reaches the Gulf of America by way of the East Fork White, the White River, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,420 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 Clifford; river miles along the main stem, rounded.
Clifford has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 22° in January. A normal year brings about 16 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Clifford normally reaches 55° and falls to 34°. The record high is 83°, in 1955; the record low 11°, in 1986. The most rain on this date, 1.71 in, fell in 1972.
Normals 1991–2020 and records since 1893 at Columbus, 9 miles south-southwest. NOAA, through RCC-ACIS.
