86° on Nov. 16, 2016, the hottest reading for this week of the year since 1890. Next is 85° in 2025.
Blanchard’s center stands about 1,270 ft above sea level. Within three miles the land runs from 1,150 ft to 1,360 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Duncan Sandstone (sandstone, conglomerate), from the Permian, 252 to 299 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 61×. 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, conglomerate. Age: Permian, 252 to 299 million years old. About 9 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 7 mi of the line.
Conglomerate, shale, siltstone. Age: Permian, 252 to 299 million years old. About 6 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Shale, sandstone, siltstone. Age: Permian, 252 to 299 million years old. About 0.4 mi of the line.

A raindrop that lands in Blanchard reaches the Gulf of America by way of Walnut Creek, the Canadian, the Arkansas and the Mississippi: about 1,180 river miles.
Lakes on the way: Murray Lake and Ozark 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 Blanchard; river miles along the main stem, rounded.
Blanchard has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 27° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Blanchard normally reaches 61° and falls to 38°. The record high is 82°, in 2025; the record low 14°, in 1916. The most rain on this date, 1.56 in, fell in 1924.
