86° on Nov. 14, 1955, the hottest reading for this week of the year since 1891. Next is 82° in 1931.
Trimble’s center stands about 300 ft above sea level. Within three miles the land runs from 270 ft to 350 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Loess (silt), from the Quaternary, less than 2.6 million years old.
The section below crosses 2 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.
Silt. Age: Quaternary, less than 2.6 million years old. About 18 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 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.
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 Trimble reaches the Gulf of America by way of Cool Springs Branch, Reeds Creek, the Obion and the Mississippi: about 890 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Trimble; river miles along the main stem, rounded.
Trimble has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 27° in January. A normal year brings about 6 inches of snow; with the rain, that comes to about 54 inches of water.
On November 14 Trimble normally reaches 59° and falls to 37°. The record high is 86°, in 1955; the record low 12°, in 2019. The most rain on this date, 2.92 in, fell in 1957.
Normals 1991–2020 and records since 1891 at Union City, 16 miles north-northeast. NOAA, through RCC-ACIS.
