76° on Nov. 11, 2020, the hottest reading for this week of the year since 1943. Next is 73° in 1949.
Porter’s center stands about 1,630 ft above sea level. Within three miles the land runs from 1,200 ft to 1,810 ft, a difference of 610 ft: hilly country. The highest named summit within 15 miles is Kinter Hill, about 2,110 ft, 14 miles southeast.
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 22×. 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. Age: Carboniferous, 299 to 324 million years old. About 14 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Shale, clastic. Age: Carboniferous, 299 to 324 million years old. About 0.4 mi of the line.

A raindrop that lands in Porter reaches the Gulf of America by way of Nye Branch, Pine Run, Mahoning Creek, the Allegheny, the Ohio and the Mississippi: about 2,030 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 Porter; river miles along the main stem, rounded.
Porter has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 17° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Porter normally reaches 50° and falls to 31°. The record high is 72°, in 1955; the record low 9°, in 1986. The most rain on this date, 1.05 in, fell in 1997.
Normals 1991–2020 and records since 1943 at Putneyville 2 SE Dam, 6 miles west, 350 ft lower. NOAA, through RCC-ACIS.
