26° on Nov. 13, 2019, the coldest reading for this week of the year since 1969. Next is 29° in 1991.
Deweyville’s center stands about 30 ft above sea level. Within three miles the land runs from 10 ft to 70 ft, a difference of 60 ft: nearly flat ground.
Under the town center the state geologic map shows Deweyville Formation (coarse-detrital, fine-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 6 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.
Sand. Age: Pleistocene, less than 2.6 million years old. About 9 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Clay. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Deweyville reaches the Gulf of America by way of the Sabine: about 60 river miles.
Lake on the way: Sabine Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Deweyville; river miles along the main stem, rounded.
Deweyville has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 40° in January. About 64 inches of rain fall in a normal year.
On November 14 Deweyville normally reaches 70° and falls to 47°. The record high is 85°, in 2005; the record low 26°, in 2019. The most rain on this date, 2.25 in, fell in 1998.
Normals 1991–2020 and records since 1969 at Orange 9 N, 5 miles south. NOAA, through RCC-ACIS.
