13° on Nov. 14, 1986, the coldest reading for this week of the year since 1891. Next is 13° in 2019.
Cannonsburg’s center stands about 630 ft above sea level. Within three miles the land runs from 590 ft to 950 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Hunts Knob, about 1,070 ft, 12 miles southwest.
Under the town center the state geologic map shows Monongahela and Conemaugh Formations, undivided (siltstone, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 35×. 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, sandstone. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Sandstone, siltstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale, siltstone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Cannonsburg reaches the Gulf of America by way of the East Fork Little Sandy, the Little Sandy, the Ohio and the Mississippi: about 1,650 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 Cannonsburg; river miles along the main stem, rounded.
Cannonsburg has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 26° in January. A normal year brings about 20 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Cannonsburg normally reaches 57° and falls to 37°. The record high is 82°, in 1993; the record low 13°, in 1986. The most rain on this date, 1.51 in, fell in 2024.
Normals 1991–2020 and records since 1891 from the Huntington Area threaded record (Huntington Tri-State Airport, 8 miles east-southeast, 190 ft higher). NOAA, through RCC-ACIS.
