5.94 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 3.17 inches, fell in 1985.
Tuscumbia’s center stands about 720 ft above sea level. Within three miles the land runs from 550 ft to 870 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is High Point, about 960 ft, 6 miles east-southeast.
Under the town center the state geologic map shows Gasconade Dolomite (dolostone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 3 rock units mapped at the surface.

A raindrop that lands in Tuscumbia reaches the Gulf of America by way of the Osage, the Missouri and the Mississippi: about 1,360 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tuscumbia; river miles along the main stem, rounded.
Tuscumbia has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 22° in January. About 45 inches of rain fall in a normal year.
On November 14 Tuscumbia normally reaches 56° and falls to 36°. The record high is 84°, in 1999; the record low 4°, in 1986. The most rain on this date, 2.22 in, fell in 1985.
