84° on Nov. 11, 2020, the hottest reading for this week of the year since 1996. Next is 80° in 2006.
Jefferson’s center stands about 600 ft above sea level. Within three miles the land runs from 570 ft to 1,070 ft, a difference of 500 ft: hilly country. The highest named summit within 15 miles is Buck Knob, about 1,360 ft, 13 miles south-southwest.
Under the town center the state geologic map shows Quaternary Alluvium (fine-detrital, coarse-detrital), 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 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.
Shale, siltstone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 11 mi of the line.
Sandstone, siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Sandstone, siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.

A raindrop that lands in Jefferson reaches the Gulf of America by way of Two and Three Quarter Mile Creek, the Kanawha, the Ohio and the Mississippi: about 1,730 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Jefferson; river miles along the main stem, rounded.
Jefferson has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 23° in January. About 48 inches of rain fall in a normal year.
On November 14 Jefferson normally reaches 57° and falls to 32°. The record high is 74°, in 2010; the record low 11°, in 2019. The most rain on this date, 0.72 in, fell in 2024.
