4.51 inches of rain fell in two days, the most for this week of the year since records began in 1923. The next wettest, 4.10 inches, fell in 1957.
Franklin’s center stands about 590 ft above sea level. Within three miles the land runs from 510 ft to 800 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Salem Knob, about 1,080 ft, 15 miles north-northwest.
Under the town center the state geologic map shows Powell 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 15 mi of the line.
Sandstone, dolostone. Age: Middle Ordovician, 459 to 471 million years old. About 6 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 3 mi of the line.

A raindrop that lands in Franklin reaches the Gulf of America by way of the Strawberry, the Black River, the White River and the Mississippi: about 990 river miles.
620 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Franklin; river miles along the main stem, rounded.
Franklin has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 24° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 52 inches of water.
On November 14 Franklin normally reaches 59° and falls to 35°. The record high is 85°, in 1999; the record low 6°, in 1986. The most rain on this date, 1.80 in, fell in 1957.
Normals 1991–2020 and records since 1923 at Evening Shade 1 NNE, 11 miles southeast. NOAA, through RCC-ACIS.
