4.21 inches of rain fell in two days, the most for this week of the year since records began in 1908. The next wettest, 3.65 inches, fell in 1985.
Fair Grove’s center stands about 1,220 ft above sea level. Within three miles the land runs from 1,090 ft to 1,360 ft, a difference of 270 ft: rolling country. The highest named summit within 15 miles is North View Hill, about 1,510 ft, 10 miles southeast.
Under the town center the state geologic map shows Smithville Dolomite, Powell Dolomite, Cotter Dolomite, Jefferson City Dolomite (dolostone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 3 rock units mapped at the surface.

Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 21 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 0.7 mi of the line.

A raindrop that lands in Fair Grove reaches the Gulf of America by way of the Little Pomme de Terre, the Pomme de Terre, the Osage, the Missouri and the Mississippi: about 1,580 river miles.
Lake on the way: Pomme de Terre Lake.
1,170 miles of the trip are on the Mississippi.

Fair Grove has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 22° in January. A normal year brings about 5 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Fair Grove normally reaches 56° and falls to 35°. The record high is 76°, in 1973; the record low 13°, in 2018. The most rain on this date, 1.15 in, fell in 1993.
Normals 1991–2020 and records since 1908 at Marshfield 4 WSW, 10 miles east-southeast, 190 ft higher. NOAA, through RCC-ACIS.
