5° on Nov. 13, 2019, the coldest reading for this week of the year since 1982. Next is 11° in 1986.
Emison’s center stands about 470 ft above sea level. Within three miles the land runs from 410 ft to 550 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Barefoot Nation Hills, about 660 ft, 6 miles east-southeast.
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 4 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 17 mi of the line.
Shale, sandstone, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 4 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 0.9 mi of the line.

A raindrop that lands in Emison reaches the Gulf of America by way of Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,230 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 Emison; river miles along the main stem, rounded.
Emison 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 8 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Emison normally reaches 56° and falls to 35°. The record high is 77°, in 1999; the record low 9°, in 2019. The most rain on this date, 2.94 in, fell in 1993.
Normals 1991–2020 and records since 1982 at Vincennes 5 NE, 5 miles south-southwest. NOAA, through RCC-ACIS.
