81° on Nov. 15, 1958, the hottest reading for this week of the year since 1891. Next is 80° in 1931.
Thompson's Station’s center stands about 800 ft above sea level. Within three miles the land runs from 700 ft to 1,040 ft, a difference of 340 ft: rolling country. The highest named summit within 15 miles is Giles Hill, about 1,220 ft, 11 miles east-southeast.
Under the town center the state geologic map shows Nashville Group; Bigby-Cannon Limestone and Hermitage Formation (limestone, calcarenite), from the Ordovician, 445 to 487 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 45×. 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, calcarenite. Age: Ordovician, 445 to 487 million years old. About 16 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.
Chert. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Shale, limestone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.

A raindrop that lands in Thompson's Station reaches the Gulf of America by way of the West Harpeth, the Harpeth, the Cumberland, the Ohio and the Mississippi: about 1,280 river miles.
Lake on the way: Bards Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Thompson's Station; river miles along the main stem, rounded.
Thompson's Station has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 28° in January. About 54 inches of rain fall in a normal year, with about 2 inches of snow.
