5.19 inches of rain fell in two days, the most for this week of the year since records began in 1980. The next wettest, 3.26 inches, fell in 2009.
Foscoe’s center stands about 3,030 ft above sea level. Within three miles the land runs from 2,730 ft to 4,500 ft, a difference of 1,770 ft: steep hill country. The highest named summit within 15 miles is Calloway Peak, about 5,920 ft, 4 miles southwest.
Under the town center the state geologic map shows Grandfather Mountain Formation; Metasiltstone, from the Neoproterozoic, 542 to 1,000 million years old.
The section below crosses 10 rock units mapped at the surface.

Gneiss. Age: Mesoproterozoic to Neoproterozoic, 950 to 1,250 million years old. About 7 mi of the line.
Metagranite. Age: Neoproterozoic, 680 to 710 million years old. About 4 mi of the line.
Metasiltstone. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Gneiss. Age: Mesoproterozoic to Neoproterozoic, 1 to 1 billion years old. About 2 mi of the line.
Metagraywacke. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 4 smaller units along the line are not listed.

A raindrop that lands in Foscoe reaches the Gulf of America by way of the Watauga, the South Fork Holston, the Holston, the Tennessee, the Ohio and the Mississippi: about 1,890 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings Lake.
970 miles of the trip are on the Mississippi.

Foscoe has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 22° in January. A normal year brings about 26 inches of snow; with the rain, that comes to about 59 inches of water.
On November 14 Foscoe normally reaches 53° and falls to 30°. The record high is 68°, in 1985; the record low 10°, in 1986. The most rain on this date, 0.57 in, fell in 2008.
Normals 1991–2020 and records since 1980 at Boone 1 SE, 8 miles east-northeast. NOAA, through RCC-ACIS.
