4.05 inches of rain fell in two days, the most for this week of the year since records began in 1896. The next wettest, 3.87 inches, fell in 1993.
Terry’s center stands about 300 ft above sea level. Within three miles the land runs from 260 ft to 390 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Catahoula formation (sand), from the Miocene, 5.3 to 23 million years old.
The section below crosses 4 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. Age: Miocene, 5.3 to 23 million years old. About 17 mi of the line.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 4 mi of the line.
Limestone. Age: Oligocene, 23 to 34 million years old. About 2 mi of the line.
Sand, clay. Age: Oligocene, 23 to 34 million years old. About 1 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 Terry reaches the Gulf of America by way of Rhodes Creek and the Pearl: about 270 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Terry; river miles along the main stem, rounded.
Terry has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 36° in January. About 57 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Terry normally reaches 68° and falls to 44°. The record high is 88°, in 1921; the record low 21°, in 1907. The most rain on this date, 2.27 in, fell in 1993.
Normals 1991–2020 and records since 1896 from the Jackson Area threaded record (Jackson International Airport, 20 miles northeast). NOAA, through RCC-ACIS.
