11° on Nov. 14, 2018, the coldest reading for this week of the year since 1973. Next is 13° in 2019.
Diamond’s center stands about 1,160 ft above sea level. Within three miles the land runs from 1,050 ft to 1,210 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Meramecian Series (limestone), from the Carboniferous, 324 to 359 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 54×. 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 15 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Diamond reaches the Gulf of America by way of Carver Branch, Shoal Creek, the Spring, the Neosho, the Arkansas and the Mississippi: about 1,180 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Diamond; river miles along the main stem, rounded.
Diamond has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 22° in January. About 47 inches of rain fall in a normal year.
On November 14 Diamond normally reaches 60° and falls to 35°. The record high is 80°, in 1999; the record low 11°, in 2018. The most rain on this date, 2.00 in, fell in 1985.
Normals 1991–2020 and records since 1973 at Diamond 2 W, 2 miles west-southwest. NOAA, through RCC-ACIS.
