4.82 inches of rain fell in two days, the most for this week of the year since records began in 1891. The next wettest, 4.68 inches, fell in 2015.
Longview’s center stands about 290 ft above sea level. Within three miles the land runs from 270 ft to 370 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Porters Creek formation (clay), from the Paleocene, 56 to 66 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 52×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay. Age: Paleocene, 56 to 66 million years old. About 12 mi of the line.
Sand, clay. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Chalk, clay. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Limestone. Age: Paleocene, 56 to 66 million years old. About 3 mi of the line.
Chalk. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.
Sand, clay, limestone. Age: Late Cretaceous, 66 to 100 million years old. About 1 mi of the line.

A raindrop that lands in Longview reaches Mobile Bay and the Gulf of America by way of Chinchahoma Creek, the Noxubee, the Tombigbee and the Mobile: about 390 river miles.
220 miles of the trip are on the Tombigbee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Longview; river miles along the main stem, rounded.
Longview has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 33° in January. About 58 inches of rain fall in a normal year.
On November 14 Longview normally reaches 66° and falls to 42°. The record high is 86°, in 1955; the record low 15°, in 1986. The most rain on this date, 2.00 in, fell in 1957.
Normals 1991–2020 and records since 1891 at State University, 9 miles east-northeast, 100 ft lower. NOAA, through RCC-ACIS.
