85° on Nov. 13, 1955, the hottest reading for this week of the year since 1919. Next is 84° in 1941.
Perryville’s center stands about 360 ft above sea level. Within three miles the land runs from 270 ft to 1,020 ft, a difference of 750 ft: hilly country. The highest named summit within 15 miles is Crystal Mountain, about 1,710 ft, 14 miles south-southwest.
Under the town center the state geologic map shows Atoka Formation - Lower part (sandstone, shale), from the Carboniferous, 299 to 324 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 19×. 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, 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 5 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.

A raindrop that lands in Perryville reaches the Gulf of America by way of the Fourche LaFave, the Arkansas and the Mississippi: about 780 river miles.
Lake on the way: Murray Lake.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Perryville; river miles along the main stem, rounded.
Perryville has a humid subtropical climate. Summer afternoons average 93° in August; winter nights fall to about 29° in January. About 51 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Perryville normally reaches 63° and falls to 39°. The record high is 84°, in 1964; the record low 16°, in 1940. The most rain on this date, 1.54 in, fell in 1926.
Normals 1991–2020 and records since 1919 at Morrilton, 10 miles north-northeast. NOAA, through RCC-ACIS.
