87° on Nov. 13, 1955, the hottest reading for this week of the year since 1892. Next is 85° in 1964.
McRae’s center stands about 230 ft above sea level. Within three miles the land runs from 210 ft to 300 ft, a difference of 90 ft: gently rolling country. The highest named summit within 15 miles is Des Arc Mountain, about 630 ft, 8 miles north-northwest.
Under the town center the state geologic map shows Terrace deposits (coarse-detrital, fine-detrital), from the Pleistocene, 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 42×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 12 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.

A raindrop that lands in McRae reaches the Gulf of America by way of Lawrence Branch, Cane Creek, Cypress Bayou, the Bayou Des Arc, the White River and the Mississippi: about 800 river miles.
620 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of McRae; river miles along the main stem, rounded.
McRae has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 30° in January. About 52 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 McRae normally reaches 62° and falls to 41°. The record high is 83°, in 1964; the record low 16°, in 1940. The most rain on this date, 2.77 in, fell in 1957.
Normals 1991–2020 and records since 1892 at Searcy, 12 miles north-northeast. NOAA, through RCC-ACIS.
