2° on Nov. 17, 1959, the coldest reading for this week of the year since 1893. Next is 5° in 1986.
Hudson’s center stands about 770 ft above sea level. Within three miles the land runs from 720 ft to 820 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Shelburn-Patoka Formations undivided (shale, limestone), from the Late Pennsylvanian, 304 to 307 million years old.
The section below crosses 2 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.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 16 mi of the line.
Shale, sandstone, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 8 mi of the line.

A raindrop that lands in Hudson reaches the Gulf of America by way of Sixmile Creek, the Mackinaw, the Illinois and the Mississippi: about 1,420 river miles.
1,190 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hudson; river miles along the main stem, rounded.
Hudson has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 16° in January. A normal year brings about 20 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Hudson normally reaches 51° and falls to 31°. The record high is 74°, in 1989; the record low 7°, in 1940. The most rain on this date, 1.10 in, fell in 1926.
Normals 1991–2020 and records since 1893 at Normal 4 NE, 4 miles south-southeast. NOAA, through RCC-ACIS.
