19° on Nov. 14, 2019, the coldest reading for this week of the year since 1982. Next is 20° in 2014.
Sedley’s center stands about 100 ft above sea level. Within three miles the land runs from 60 ft to 140 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Windsor Formation (fine-detrital, coarse-detrital), from the Tertiary to Quaternary, less than 66 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Fine-detrital, coarse-detrital. Age: Tertiary to Quaternary, less than 66 million years old. About 13 mi of the line.
Unconsolidated. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Sand. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Gravel. Age: Tertiary, 2.6 to 66 million years old. About 2 mi of the line.
Sand, silt, clay. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.
Sand, silt, clay. Age: Tertiary, 2.6 to 66 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Sedley reaches Albemarle Sound and the Atlantic Ocean by way of Cypress Swamp, the Blackwater and the Chowan: about 80 river miles.
50 miles of the trip are on the Chowan.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sedley; river miles along the main stem, rounded.
Sedley has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 28° in January. A normal year brings about 6 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Sedley normally reaches 62° and falls to 38°. The record high is 78°, in 2007; the record low 19°, in 2019. The most rain on this date, 1.30 in, fell in 1995.
Normals 1991–2020 and records since 1982 at Wakefield 1 NW, 14 miles north. NOAA, through RCC-ACIS.
