77° on Nov. 13, 1949, the hottest reading for this week of the year since 1931. Next is 77° in 2020.
West Shenango’s center stands about 1,060 ft above sea level. Within three miles the land runs from 1,000 ft to 1,280 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Wheeler Hill, about 1,410 ft, 12 miles southeast.
Under the town center the state geologic map shows Cuyahoga Group (siltstone, shale), from the Carboniferous, 324 to 359 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 38×. 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: Devonian to Carboniferous, 324 to 422 million years old. About 8 mi of the line.

A raindrop that lands in West Shenango reaches the Gulf of America by way of the Pymatuning Swamp (historical), the Shenango, the Beaver, the Ohio and the Mississippi: about 2,010 river miles.
Lake on the way: Pymatuning Swamp (historical).
970 miles of the trip are on the Mississippi.

West Shenango 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 62 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 West Shenango normally reaches 50° and falls to 32°. The record high is 70°, in 1989; the record low 13°, in 1933. The most rain on this date, 1.22 in, fell in 1972.
