4° on Nov. 12, 2019, the coldest reading for this week of the year since 1931. Next is 6° in 1986.
Tarrants’s center stands about 770 ft above sea level. Within three miles the land runs from 630 ft to 920 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Buffalo Knob, about 1,030 ft, 9 miles southeast.
Under the town center the state geologic map shows Silurian system (limestone), from the Silurian, 422 to 445 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 43×. 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, siltstone. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Limestone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 4 mi of the line.
Limestone. Age: Silurian, 422 to 445 million years old. About 4 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 454 to 459 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Tarrants reaches the Gulf of America by way of Noix Creek and the Mississippi: about 1,260 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tarrants; river miles along the main stem, rounded.
Tarrants has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 18° in January. A normal year brings about 16 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Tarrants normally reaches 53° and falls to 34°. The record high is 79°, in 1989; the record low 9°, in 1986. The most rain on this date, 2.06 in, fell in 1985.
