22° on Nov. 13, 2019, the coldest reading for this week of the year since 1984. Next is 26° in 2014.
Troup’s center stands about 480 ft above sea level. Within three miles the land runs from 330 ft to 560 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Snow Mountain, about 660 ft, 9 miles west-southwest.
Under the town center the state geologic map shows Queen City Sand (siltstone, sandstone), from the Middle Eocene, 38 to 48 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 57×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Eocene, 34 to 56 million years old. About 10 mi of the line.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 9 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Sandstone. Age: Middle Eocene, 38 to 48 million years old. About 1 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 0.7 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 Troup reaches the Gulf of America by way of Caney Creek, Mud Creek, the Angelina and the Neches: about 320 river miles.
Lakes on the way: Ester Lake, Sabine Lake and B A Steinhagen Lake.
110 miles of the trip are on the Neches.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Troup; river miles along the main stem, rounded.
Troup has a humid subtropical climate. Summer afternoons average 94° in August; winter nights fall to about 38° in January. About 48 inches of rain fall in a normal year.
On November 14 Troup normally reaches 67° and falls to 47°. The record high is 83°, in 2007; the record low 27°, in 2018. The most rain on this date, 0.54 in, fell in 1998.
Normals 1991–2020 and records since 1984 at Tyler, 15 miles northwest. NOAA, through RCC-ACIS.
