9° on Nov. 13, 2019, the coldest reading for this week of the year since 1896. Next is 12° in 1959.
Cadiz’s center stands about 430 ft above sea level. Within three miles the land runs from 350 ft to 540 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Buie Knob, about 800 ft, 11 miles east-northeast.
Under the town center the state geologic map shows Ste. Genevieve and St. Louis Limestones, undivided, from the Carboniferous, 324 to 359 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 59×. 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. Age: Carboniferous, 324 to 359 million years old. About 20 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
Limestone, sandstone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.

A raindrop that lands in Cadiz reaches the Gulf of America by way of the Little River, the Cumberland, the Ohio and the Mississippi: about 1,100 river miles.
Lake on the way: Bards Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cadiz; river miles along the main stem, rounded.
Cadiz has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 27° in January. A normal year brings about 5 inches of snow; with the rain, that comes to about 52 inches of water.
On November 14 Cadiz normally reaches 59° and falls to 38°. The record high is 82°, in 1955; the record low 15°, in 1986. The most rain on this date, 2.72 in, fell in 1957.
Normals 1991–2020 and records since 1896 at Hopkinsville, 17 miles east. NOAA, through RCC-ACIS.
