The Nebo plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
10° on Nov. 17, 1959, the coldest reading for this week of the year since 1946. Next is 10° in 2019.
Nebo’s center stands about 410 ft above sea level. Within three miles the land runs from 360 ft to 490 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Walnut Hill, about 660 ft, 14 miles west-southwest.
Under the town center the state geologic map shows Sturgis Formation (siltstone), from the Carboniferous, 299 to 324 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 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.
Siltstone. Age: Carboniferous, 299 to 324 million years old. About 15 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Siltstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Siltstone. Age: Carboniferous, 299 to 324 million years old. About 0.6 mi of the line.

A raindrop that lands in Nebo reaches the Gulf of America by way of Rose Creek, Clear Creek, the Tradewater, the Ohio and the Mississippi: about 1,140 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Nebo; river miles along the main stem, rounded.
Nebo has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 28° in January. About 52 inches of rain fall in a normal year.
On November 14 Nebo normally reaches 59° and falls to 40°. The record high is 77°, in 1990; the record low 12°, in 1986. The most rain on this date, 3.70 in, fell in 1957.
Normals 1991–2020 and records since 1946 at Madisonville, 7 miles east-southeast. NOAA, through RCC-ACIS.
