5.63 inches of rain fell in two days, the most for this week of the year since records began in 1880. The next wettest, 3.58 inches, fell in 2022.
Morganton’s center stands about 1,160 ft above sea level. Within three miles the land runs from 1,010 ft to 1,270 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Table Rock Mountain, about 3,870 ft, 15 miles northwest.
Under the town center the state geologic map shows Migmatitic Granitic Gneiss (biotite-gneiss), from the Cambrian to Ordovician, 445 to 542 million years old.
The section below crosses 5 rock units mapped at the surface.

Biotite-gneiss, mica-schist, calc-silicate-rock. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 10 mi of the line.
Biotite-gneiss. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 0.8 mi of the line.
Biotite-gneiss. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 0.6 mi of the line.

A raindrop that lands in Morganton reaches the Atlantic Ocean by way of the Catawba, the Wateree, the Congaree, the Santee and the South Santee: about 400 river miles.
Lakes on the way: Lib Pines Lake and Lake Norman.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Morganton; river miles along the main stem, rounded.
Morganton has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 28° in January. About 52 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Morganton normally reaches 61° and falls to 35°. The record high is 80°, in 1999; the record low 14°, in 1986. The most rain on this date, 1.86 in, fell in 1972.
