4.37 inches of rain fell in two days, the most for this week of the year since records began in 1912. The next wettest, 4.32 inches, fell in 2020.
New Castle’s center stands about 1,340 ft above sea level. Within three miles the land runs from 1,240 ft to 2,950 ft, a difference of 1,710 ft: steep hill country. The highest named summit within 15 miles is Arnolds Knob, about 3,890 ft, 13 miles west.
Under the town center the state geologic map shows Millboro Shale and Needmore Formation (shale, black-shale), from the Devonian, 359 to 422 million years old.
The section below crosses 14 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone. Age: Devonian, 359 to 422 million years old. About 6 mi of the line.
Shale, black-shale. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Arenite, shale, sandstone. Age: Silurian, 422 to 445 million years old. About 3 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Limestone. Age: Silurian to Devonian, 359 to 445 million years old. About 2 mi of the line.
Shale, sandstone. Age: Devonian, 359 to 422 million years old. 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. 8 smaller units along the line are not listed.

A raindrop that lands in New Castle reaches Chesapeake Bay and the Atlantic Ocean by way of Johns Creek, Craig Creek and the James: about 370 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Castle; river miles along the main stem, rounded.
New Castle has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 29° in January. A normal year brings about 15 inches of snow; with the rain, that comes to about 43 inches of water.
On November 14 New Castle normally reaches 60° and falls to 38°. The record high is 82°, in 1993; the record low 13°, in 1986. The most rain on this date, 1.68 in, fell in 1972.
Normals 1991–2020 and records since 1912 from the Roanoke Area threaded record (Roanoke-Blacksburg Regional Airport, 15 miles south-southeast, 200 ft lower). NOAA, through RCC-ACIS.
