9.80 inches of rain fell in two days, the most for this week of the year since records began in 1948. The next wettest, 5.75 inches, fell in 1948.
Edwards’s center stands about 250 ft above sea level. Within three miles the land runs from 130 ft to 320 ft, a difference of 190 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 2 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.
Limestone. Age: Oligocene, 23 to 34 million years old. About 13 mi of the line.
Sand. Age: Miocene, 5.3 to 23 million years old. About 11 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Edwards reaches the Gulf of America by way of the Big Black and the Mississippi: about 490 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Edwards; river miles along the main stem, rounded.
Edwards has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 38° in January. About 53 inches of rain fall in a normal year.
On November 14 Edwards normally reaches 68° and falls to 44°. The record high is 85°, in 1955; the record low 20°, in 2013. The most rain on this date, 1.59 in, fell in 1970.
Normals 1991–2020 and records since 1948 from the Tallulah-Vicksburg Area threaded record (Tallulah Vicksburg Regional Airport, 25 miles west, 170 ft lower). NOAA, through RCC-ACIS.
