13° on Nov. 13, 2019, the coldest reading for this week of the year since 1891. Next is 14° in 1916.
Three Way’s center stands about 430 ft above sea level. Within three miles the land runs from 330 ft to 510 ft, a difference of 180 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 3 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 13 mi of the line.
Sand. Age: Tertiary, 2.6 to 66 million years old. About 6 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 5 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 Three Way reaches the Gulf of America by way of the Middle Fork Forked Deer, the North Fork Forked Deer, the Forked Deer, the Obion and the Mississippi: about 910 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Three Way; river miles along the main stem, rounded.
Three Way has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 27° in January. About 57 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Three Way normally reaches 62° and falls to 37°. The record high is 80°, in 1985; the record low 15°, in 2019. The most rain on this date, 4.15 in, fell in 1915.
Normals 1991–2020 and records since 1891 at Jackson Experiment Sta, 10 miles south. NOAA, through RCC-ACIS.
