1° on Nov. 13, 2019, the coldest reading for this week of the year since 1893. Next is 4° in 1959.
Judson’s center stands about 620 ft above sea level. Within three miles the land runs from 590 ft to 790 ft, a difference of 200 ft: rolling country. The highest named summit within 15 miles is Truax Hill, about 820 ft, 13 miles north-northeast.
Under the town center the state geologic map shows Raccoon Creek Group (shale, sandstone), from the Carboniferous, 299 to 324 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 51×. 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, sandstone. Age: Carboniferous, 299 to 324 million years old. About 14 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 5 mi of the line.

A raindrop that lands in Judson reaches the Gulf of America by way of Little Raccoon Creek, Raccoon Creek, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,360 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 Judson; river miles along the main stem, rounded.
Judson has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 17° in January. A normal year brings about 13 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Judson normally reaches 53° and falls to 32°. The record high is 76°, in 1931; the record low 9°, in 1986. The most rain on this date, 3.72 in, fell in 1993.
Normals 1991–2020 and records since 1893 at Rockville, 6 miles southwest. NOAA, through RCC-ACIS.
