22° on Nov. 13, 2019, the coldest reading for this week of the year since 1995. Next is 25° in 1997.
Douglas’s center stands about 940 ft above sea level. Within three miles the land runs from 810 ft to 980 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Aurora Mountain, about 1,400 ft, 8 miles east.
Under the town center the state geologic map shows Pottsville Formation (sandstone, conglomerate), from the Carboniferous, 299 to 324 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 25×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 16 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 1 mi of the line.
Dolostone, limestone. Age: Cambrian to Ordovician, 445 to 542 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. 2 smaller units along the line are not listed.
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 Douglas reaches Mobile Bay and the Gulf of America by way of Little Mud Creek, Big Mud Creek, the Locust Fork, the Black Warrior, the Tombigbee and the Mobile: about 520 river miles.
170 miles of the trip are on the Tombigbee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Douglas; river miles along the main stem, rounded.
Douglas has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 32° in January. About 57 inches of rain fall in a normal year.
On November 14 Douglas normally reaches 62° and falls to 43°. The record high is 74°, in 2011; the record low 22°, in 2019. The most rain on this date, 1.27 in, fell in 2024.
Normals 1991–2020 and records since 1995 at Guntersville No.2, 11 miles north, 340 ft lower. NOAA, through RCC-ACIS.
