3.05 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 2.78 inches, fell in 1985.
Sedalia’s center stands about 910 ft above sea level. Within three miles the land runs from 770 ft to 920 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Osagean Series (limestone), from the Carboniferous, 324 to 359 million years old.
The section below crosses 5 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.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 10 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 7 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Limestone, sandstone. Age: Early Devonian to Late Devonian, 359 to 422 million years old. About 1 mi of the line.

A raindrop that lands in Sedalia reaches the Gulf of America by way of Brushy Creek, Muddy Creek, the Lamine, the Missouri and the Mississippi: about 1,440 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sedalia; river miles along the main stem, rounded.
Sedalia has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 19° in January. A normal year brings about 13 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Sedalia normally reaches 54° and falls to 33°. The record high is 79°, in 1964; the record low 7°, in 2018. The most rain on this date, 1.22 in, fell in 1993.
