3.32 inches of rain fell in two days, the most for this week of the year since records began in 1979. The next wettest, 2.81 inches, fell in 2009.
Telford’s center stands about 1,700 ft above sea level. Within three miles the land runs from 1,410 ft to 1,850 ft, a difference of 440 ft: hilly country. The highest named summit within 15 miles is Green Ridge Knob, about 4,840 ft, 15 miles south-southwest.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, dolostone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 15 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Sandstone, arkose, conglomerate. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Shale, sandstone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Siltstone. Age: Precambrian. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Telford reaches the Gulf of America by way of Little Limestone Creek, the Nolichucky, the French Broad, the Tennessee, the Ohio and the Mississippi: about 1,810 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.

Telford has a humid subtropical climate. Summer afternoons average 85° in July; winter nights fall to about 24° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Telford normally reaches 59° and falls to 32°. The record high is 73°, in 2005; the record low 15°, in 2019. The most rain on this date, 0.40 in, fell in 1986.
Normals 1991–2020 and records since 1979 at Erwin 1 W, 10 miles southeast. NOAA, through RCC-ACIS.
