80° on Nov. 17, 1958, the hottest reading for this week of the year since 1893. Next is 79° in 1964.
Tullahoma’s center stands about 1,070 ft above sea level. Within three miles the land runs from 1,000 ft to 1,140 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Little Mountain, about 1,250 ft, 12 miles southeast.
Under the town center the state geologic map shows St. Louis Limestone and Warsaw Limestone, from the Carboniferous, 324 to 359 million years old.
The section below crosses 5 rock units mapped at the surface.

Limestone. Age: Carboniferous, 324 to 359 million years old. About 15 mi of the line.
Chert. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Limestone, calcarenite. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Shale, limestone. Age: Ordovician, 445 to 487 million years old. About 0.8 mi of the line.

A raindrop that lands in Tullahoma reaches the Gulf of America by way of Rock Creek, the Elk River, the Tennessee, the Ohio and the Mississippi: about 1,460 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical) and Pickwick Lake.
970 miles of the trip are on the Mississippi.

Tullahoma has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 29° in January. About 61 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Tullahoma normally reaches 60° and falls to 37°. The record high is 79°, in 1964; the record low 18°, in 1907. The most rain on this date, 1.64 in, fell in 1915.
