9° on Nov. 13, 2019, the coldest reading for this week of the year since 1897. Next is 10° in 1959.
Highland’s center stands about 490 ft above sea level. Within three miles the land runs from 370 ft to 510 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Big Ditney Hill, about 680 ft, 13 miles east-northeast.
Under the town center the state geologic map shows Patoka and Shelburn Formations (shale, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 3 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, sandstone. Age: Carboniferous, 299 to 324 million years old. About 19 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Highland reaches the Gulf of America by way of Little Pigeon Creek, Pigeon Creek, the Ohio and the Mississippi: about 1,160 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 Highland; river miles along the main stem, rounded.
Highland has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 25° in January. A normal year brings about 11 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Highland normally reaches 57° and falls to 37°. The record high is 77°, in 1971; the record low 11°, in 1986. The most rain on this date, 2.40 in, fell in 1993.
Normals 1991–2020 and records since 1897 from the Evansville Area threaded record (Evansville Regional Airport, 3 miles east-northeast). NOAA, through RCC-ACIS.
