17° on Nov. 13, 2019, the coldest reading for this week of the year since 1948. Next is 19° in 1960.
Willisville’s center stands about 380 ft above sea level. Within three miles the land runs from 300 ft to 400 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Claibourne Group (sand, clay), from the Middle Eocene, 38 to 48 million years old.
The section below crosses 3 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, clay. Age: Middle Eocene, 38 to 48 million years old. About 14 mi of the line.
Sand, fine-detrital. Age: Early Eocene, 48 to 56 million years old. About 6 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 5 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 Willisville reaches the Gulf of America by way of Brushy Creek, Cypress Creek, the Bayou Dorcheat, Loggy Bayou, the Red River, the Atchafalaya and the Lower Atchafalaya: about 500 river miles.
Lake on the way: Tadpole Lake.
230 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Willisville; river miles along the main stem, rounded.
Willisville has a humid subtropical climate. Summer afternoons average 93° in August; winter nights fall to about 31° in January. About 56 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Willisville normally reaches 66° and falls to 40°. The record high is 87°, in 1955; the record low 19°, in 1963. The most rain on this date, 2.10 in, fell in 1970.
Normals 1991–2020 and records since 1948 at Magnolia, 19 miles south-southeast. NOAA, through RCC-ACIS.
