90° on Nov. 16, 2025, the hottest reading for this week of the year since 1953. Next is 84° in 1999.
Pocasset’s center stands about 1,190 ft above sea level. Within three miles the land runs from 1,130 ft to 1,280 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Red Hill, about 1,430 ft, 6 miles north.
Under the town center the state geologic map shows Dog Creek Shale, from the Permian, 252 to 299 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 47×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Permian, 252 to 299 million years old. About 8 mi of the line.
Conglomerate, shale, siltstone. Age: Permian, 252 to 299 million years old. About 6 mi of the line.
Sandstone. Age: Permian, 252 to 299 million years old. About 4 mi of the line.
Sandstone, conglomerate. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Sandstone, siltstone. Age: Permian, 252 to 299 million years old. About 2 mi of the line.

A raindrop that lands in Pocasset reaches the Gulf of America by way of West Fork Salt Creek, Salt Creek, the Washita, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,070 river miles.
680 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pocasset; river miles along the main stem, rounded.
Pocasset has a humid subtropical climate. Summer afternoons average 97° in July; winter nights fall to about 27° in January. About 37 inches of rain fall in a normal year, with about 5 inches of snow.
On November 14 Pocasset normally reaches 65° and falls to 39°. The record high is 83°, in 2025; the record low 17°, in 1959. The most rain on this date, 0.74 in, fell in 1993.
Normals 1991–2020 and records since 1953 at Chickasha Experiment Station, 10 miles south-southeast, 100 ft lower. NOAA, through RCC-ACIS.
