22° on Nov. 13, 2019, the coldest reading for this week of the year since 1968. Next is 25° in 1969.
Texarkana’s center stands about 370 ft above sea level. Within three miles the land runs from 280 ft to 390 ft, a difference of 110 ft: gently rolling country.
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 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.
Sand, fine-detrital. Age: Early Eocene, 48 to 56 million years old. About 7 mi of the line.
Clay, sand. Age: Paleocene to Eocene, 34 to 66 million years old. About 5 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Mudstone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 2 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 Texarkana reaches the Gulf of America by way of Nix Creek, Days Creek, the Sulphur, the Red River, the Atchafalaya and the Lower Atchafalaya: about 500 river miles.
320 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Texarkana; river miles along the main stem, rounded.
Texarkana has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 33° in January. About 52 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Texarkana normally reaches 65° and falls to 43°. The record high is 83°, in 2005; the record low 22°, in 2019. The most rain on this date, 1.92 in, fell in 1970.
Normals 1991–2020 and records since 1968 at Texarkana, 2 miles west. NOAA, through RCC-ACIS.
