85° on Nov. 17, 1958, the hottest reading for this week of the year since 1890. Next is 83° in 1909.
Alexandria’s center stands about 680 ft above sea level. Within three miles the land runs from 610 ft to 1,010 ft, a difference of 400 ft: rolling country. The highest named summit within 15 miles is Short Mountain, about 2,140 ft, 15 miles south-southeast.
Under the town center the state geologic map shows Stones River Group; Carters Limestone, from the Ordovician, 445 to 487 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 26×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Alexandria reaches the Gulf of America by way of Hickman Creek, the Caney Fork, the Cumberland, the Ohio and the Mississippi: about 1,360 river miles.
Lake on the way: Bards Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Alexandria; river miles along the main stem, rounded.
Alexandria has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 27° in January. About 52 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Alexandria normally reaches 62° and falls to 36°. The record high is 82°, in 1909; the record low 17°, in 2012. The most rain on this date, 2.50 in, fell in 1915.
