83° on Nov. 11, 1989, the hottest reading for this week of the year since 1871. Next is 81° in 1958.
Belle Meade’s center stands about 580 ft above sea level. Within three miles the land runs from 460 ft to 960 ft, a difference of 500 ft: hilly country. The highest named summit within 15 miles is Pleasant Hill Knob, about 1,210 ft, 14 miles south-southeast.
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 26×. 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 12 mi of the line.
Shale, limestone. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Chert. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Belle Meade reaches the Gulf of America by way of Richland Creek, the Cumberland, the Ohio and the Mississippi: about 1,210 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 Belle Meade; river miles along the main stem, rounded.
Belle Meade has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 30° in January. About 50 inches of rain fall in a normal year, with about 5 inches of snow.
On November 14 Belle Meade normally reaches 62° and falls to 39°. The record high is 80°, in 1973; the record low 18°, in 1986. The most rain on this date, 3.79 in, fell in 1915.
