11° on Nov. 12, 2019, the coldest reading for this week of the year since 1936. Next is 12° in 1940.
South Fulton’s center stands about 360 ft above sea level. Within three miles the land runs from 340 ft to 470 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Loess (silt), from the Quaternary, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Silt. Age: Quaternary, less than 2.6 million years old. About 12 mi of the line.
Fine-detrital. Age: Tertiary to Holocene, less than 66 million years old. About 10 mi of the line.
Sandstone, siltstone. Age: Tertiary, 2.6 to 66 million years old. About 1 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.4 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 0.2 mi of the line.

A raindrop that lands in South Fulton reaches the Gulf of America by way of Harris Fork Creek, the North Fork Obion, the Obion and the Mississippi: about 920 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of South Fulton; river miles along the main stem, rounded.
South Fulton has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 26° in January. About 55 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 South Fulton normally reaches 60° and falls to 38°. The record high is 80°, in 1978; the record low 14°, in 1986. The most rain on this date, 1.71 in, fell in 1959.
Normals 1991–2020 and records since 1936 at Martin U Of T Branch Experiment Station, 10 miles south. NOAA, through RCC-ACIS.
