−1° on Nov. 15, 1959, the coldest reading for this week of the year since 1871. Next is 3° in 1933.
Lynn Center’s center stands about 750 ft above sea level. Within three miles the land runs from 660 ft to 790 ft, a difference of 130 ft: gently rolling country.
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 64×. 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, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 17 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 7 mi of the line.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 0.8 mi of the line.

A raindrop that lands in Lynn Center reaches the Gulf of America by way of the Edwards and the Mississippi: about 1,460 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lynn Center; river miles along the main stem, rounded.
Lynn Center has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 15° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Lynn Center normally reaches 50° and falls to 31°. The record high is 75°, in 1971; the record low 0°, in 1959. The most rain on this date, 1.16 in, fell in 1968.
