20° on Nov. 13, 2013, the coldest reading for this week of the year since 1948. Next is 21° in 1997.
Centerville’s center stands about 840 ft above sea level. Within three miles the land runs from 650 ft to 840 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Biotite-plagioclase-quartz gneiss and biotite-muscovite schist (biotite-gneiss, mica-schist), from the Neoproterozoic to Cambrian, 487 to 1,000 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 55×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Biotite-gneiss, mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 22 mi of the line.
Metagabbro. Age: Paleozoic, 252 to 542 million years old. About 0.9 mi of the line.
Gneiss. Age: Ordovician to Silurian, 422 to 487 million years old. About 0.8 mi of the line.
Gneiss. Age: Ordovician, 445 to 487 million years old. About 0.4 mi of the line.

A raindrop that lands in Centerville reaches the Atlantic Ocean by way of Little Beaverdam Creek and the Savannah: about 310 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Centerville; river miles along the main stem, rounded.
Centerville has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 33° in January. About 46 inches of rain fall in a normal year.
On November 14 Centerville normally reaches 64° and falls to 41°. The record high is 79°, in 2007; the record low 22°, in 2013. The most rain on this date, 1.44 in, fell in 1961.
