71° on Nov. 14, 1999, the hottest reading for this week of the year since 1948. Next is 69° in 1990.
Ridgeland’s center stands about 1,130 ft above sea level. Within three miles the land runs from 1,030 ft to 1,240 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 48×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 24 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 Ridgeland reaches the Gulf of America by way of South Fork Lower Pine Creek, Lower Pine Creek, the Red Cedar, the Chippewa and the Mississippi: about 1,840 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ridgeland; river miles along the main stem, rounded.
Ridgeland has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 2° in January. A normal year brings about 51 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Ridgeland normally reaches 41° and falls to 24°. The record high is 71°, in 1999; the record low 3°, in 1996. The most rain on this date, 1.00 in, fell in 2010.
