10° on Nov. 13, 1986, the coldest reading for this week of the year since 1949. Next is 10° in 2019.
Symsonia’s center stands about 410 ft above sea level. Within three miles the land runs from 330 ft to 490 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Continental deposits and loess, undifferentiated (fine-detrital), from the Tertiary to Holocene, less than 66 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.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 14 mi of the line.
Fine-detrital. Age: Tertiary to Holocene, less than 66 million years old. About 10 mi of the line.
Sandstone, siltstone. 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.

A raindrop that lands in Symsonia reaches the Gulf of America by way of Bear Creek, the West Fork Clarks, the Clarks, the Tennessee, the Ohio and the Mississippi: about 1,050 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Symsonia; river miles along the main stem, rounded.
Symsonia has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 27° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Symsonia normally reaches 59° and falls to 38°. The record high is 77°, in 2025; the record low 12°, in 1986. The most rain on this date, 1.50 in, fell in 1958.
Normals 1991–2020 and records since 1949 at Paducah Barkley Regional Airport, 17 miles northwest. NOAA, through RCC-ACIS.
