75° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 72° in 2012.
Kersey’s center stands about 1,960 ft above sea level. Within three miles the land runs from 1,690 ft to 2,230 ft, a difference of 540 ft: hilly country. The highest named summit within 15 miles is Boone Mountain, about 2,410 ft, 8 miles south-southwest.
Under the town center the state geologic map shows Allegheny Formation (sandstone), 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 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 10 mi of the line.
Sandstone, siltstone, shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 7 mi of the line.

A raindrop that lands in Kersey reaches the Gulf of America by way of Daguscahonda Run, Elk Creek, the Clarion, the Allegheny, the Ohio and the Mississippi: about 2,140 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Kersey; river miles along the main stem, rounded.
Kersey has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 16° in January. A normal year brings about 53 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Kersey normally reaches 50° and falls to 30°. The record high is 68°, in 2010; the record low 7°, in 1996. The most rain on this date, 1.40 in, fell in 1972.
Normals 1991–2020 and records since 1893 at Ridgway, 9 miles west-northwest, 600 ft lower. NOAA, through RCC-ACIS.
