3.41 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 3.02 inches, fell in 1985.
Tuscola’s center stands about 650 ft above sea level. Within three miles the land runs from 640 ft to 680 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows New Albany Shale, Blocher Shale, Sylamore Sandstone, Selmier Shale, Sweetland Creek Shale, Grassy Creek Shale, Saverton Shale, and Louisiana Limestone, from the Middle Devonian to Late Devonian, 359 to 388 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 57×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Pennsylvanian, 304 to 307 million years old. About 9 mi of the line.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 8 mi of the line.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 3 mi of the line.
Shale, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 2 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 1 mi of the line.
Shale. Age: Middle Devonian to Late Devonian, 359 to 388 million years old. About 0.8 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.

A raindrop that lands in Tuscola reaches the Gulf of America by way of the Scattering Fork, the Embarras, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,380 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tuscola; river miles along the main stem, rounded.
Tuscola has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 18° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Tuscola normally reaches 52° and falls to 33°. The record high is 77°, in 1971; the record low 9°, in 2019. The most rain on this date, 2.20 in, fell in 1993.
