5° on Nov. 15, 1933, the coldest reading for this week of the year since 1893. Next is 6° in 1959.
Shelby’s center stands about 810 ft above sea level. Within three miles the land runs from 670 ft to 1,010 ft, a difference of 340 ft: rolling country.
Under the town center the state geologic map shows Marshall Sandstone, from the Carboniferous, 324 to 359 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. 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, 324 to 359 million years old. About 11 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 7 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.

A raindrop that lands in Shelby reaches Lake Michigan by way of Piper Creek and Stony Creek: about 11 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Shelby; river miles along the main stem, rounded.
Shelby has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 16° in January. A normal year brings about 78 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Shelby normally reaches 46° and falls to 31°. The record high is 65°, in 1895; the record low 10°, in 1933. The most rain on this date, 1.15 in, fell in 1991.
Normals 1991–2020 and records since 1893 at Hart 3 WSW, 5 miles northwest. NOAA, through RCC-ACIS.
