5.08 inches of rain fell in two days, the most for this week of the year since records began in 1889. The next wettest, 2.96 inches, fell in 1992.
Lupus’s center stands about 580 ft above sea level. Within three miles the land runs from 560 ft to 810 ft, a difference of 250 ft: rolling country.
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 56×. 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: Carboniferous, 324 to 359 million years old. About 14 mi of the line.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Limestone, sandstone. Age: Early Devonian to Late Devonian, 359 to 422 million years old. About 0.7 mi of the line.

A raindrop that lands in Lupus reaches the Gulf of America by way of Splice Creek, the Missouri and the Mississippi: about 1,340 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lupus; river miles along the main stem, rounded.
Lupus has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 22° in January. A normal year brings about 16 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Lupus normally reaches 55° and falls to 36°. The record high is 79°, in 2025; the record low 10°, in 1940. The most rain on this date, 1.68 in, fell in 1913.
Normals 1991–2020 and records since 1889 from the Columbia Area threaded record (Columbia Regional Airport, 13 miles east, 310 ft higher). NOAA, through RCC-ACIS.
