80° on Nov. 11, 2002, the hottest reading for this week of the year since 1942. Next is 79° in 1955.
Greenbrier’s center stands about 850 ft above sea level. Within three miles the land runs from 670 ft to 910 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows St. Louis Limestone and Warsaw Limestone, from the Carboniferous, 324 to 359 million years old.
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 38×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 14 mi of the line.
Shale, limestone. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Chert. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Limestone. Age: Silurian, 422 to 445 million years old. About 1 mi of the line.

A raindrop that lands in Greenbrier reaches the Gulf of America by way of Long Branch, the Sulphur Fork Red, the Red River, the Cumberland, the Ohio and the Mississippi: about 1,220 river miles.
Lake on the way: Bards Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Greenbrier; river miles along the main stem, rounded.
Greenbrier has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 27° in January. A normal year brings about 6 inches of snow; with the rain, that comes to about 53 inches of water.
On November 14 Greenbrier normally reaches 59° and falls to 38°. The record high is 77°, in 1999; the record low 15°, in 2019. The most rain on this date, 1.87 in, fell in 1951.
Normals 1991–2020 and records since 1942 at Springfield Experiment Station, 4 miles northwest, 100 ft lower. NOAA, through RCC-ACIS.
