81° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 80° in 1985.
Vonore’s center stands about 860 ft above sea level. Within three miles the land runs from 810 ft to 1,070 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Salt Spring Mountain, about 3,160 ft, 14 miles southeast.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 21×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, limestone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 5 mi of the line.
Dolostone, limestone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.

A raindrop that lands in Vonore reaches the Gulf of America by way of the Tennessee, the Ohio and the Mississippi: about 1,620 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings 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 Vonore; river miles along the main stem, rounded.
Vonore has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 28° in January. About 55 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Vonore normally reaches 62° and falls to 37°. The record high is 80°, in 1985; the record low 19°, in 2019. The most rain on this date, 0.82 in, fell in 2024.
Normals 1991–2020 and records since 1948 at Lenoir City, 14 miles north. NOAA, through RCC-ACIS.
