−10° on Nov. 15, 1933, the coldest reading for this week of the year since 1913. Next is −10° in 1959.
Briley’s center stands about 900 ft above sea level. Within three miles the land runs from 870 ft to 1,300 ft, a difference of 430 ft: hilly country. The highest named summit within 15 miles is Comstock Hills, about 1,460 ft, 13 miles south-southwest.
Under the town center the state geologic map shows Bedford Shale, from the Late Devonian, 359 to 384 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 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Black-shale. Age: Late Devonian, 359 to 384 million years old. About 11 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 9 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 5 mi of the line.

A raindrop that lands in Briley reaches Lake Huron by way of Haymeadow Creek and the Thunder Bay: about 65 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.

Briley has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 6° in February. A normal year brings about 84 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Briley normally reaches 43° and falls to 26°. The record high is 63°, in 1999; the record low 7°, in 1996. The most rain on this date, 0.68 in, fell in 1992.
Normals 1991–2020 and records since 1913 at Vanderbilt 11 ENE, 16 miles northwest. NOAA, through RCC-ACIS.
