10° on Nov. 13, 2019, the coldest reading for this week of the year since 1938. Next is 12° in 1986.
Shelby’s center stands about 620 ft above sea level. Within three miles the land runs from 540 ft to 680 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Lockport Group (dolostone), from the Silurian, 425 to 434 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 32×. 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. Age: Late Ordovician, 445 to 459 million years old. About 7 mi of the line.
Shale. Age: Silurian, 422 to 428 million years old. About 7 mi of the line.
Dolostone. Age: Silurian, 425 to 434 million years old. About 4 mi of the line.
Limestone. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 3 mi of the line.
Sandstone, shale. Age: Silurian, 434 to 445 million years old. About 2 mi of the line.
Shale. Age: Silurian, 428 to 445 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
Shelby has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 18° in January. A normal year brings about 67 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Shelby normally reaches 50° and falls to 33°. The record high is 71°, in 1994; the record low 12°, in 1986. The most rain on this date, 0.85 in, fell in 1997.
Normals 1991–2020 and records since 1938 at Albion, 9 miles east-northeast. NOAA, through RCC-ACIS.
