83° on Nov. 13, 1999, the hottest reading for this week of the year since 1885. Next is 80° in 2016.
Concordia’s center stands about 1,390 ft above sea level. Within three miles the land runs from 1,330 ft to 1,560 ft, a difference of 230 ft: rolling country.
Under the town center the state geologic map shows Alluvium (sand, silt, clay), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. 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, shale. Age: Late Cretaceous, 66 to 100 million years old. About 11 mi of the line.
Silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 9 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Claystone, mudstone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 0.2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Concordia reaches the Gulf of America by way of the Republican, the Kansas, the Missouri and the Mississippi: about 1,800 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 Concordia; river miles along the main stem, rounded.
Concordia has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 19° in January. A normal year brings about 19 inches of snow; with the rain, that comes to about 28 inches of water.
On November 14 Concordia normally reaches 54° and falls to 32°. The record high is 76°, in 2025; the record low 0°, in 1940. The most rain on this date, 0.74 in, fell in 1926.
