86° on Nov. 14, 1999, the hottest reading for this week of the year since 1893. Next is 83° in 2016.
Edmond’s center stands about 2,130 ft above sea level. Within three miles the land runs from 2,080 ft to 2,310 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Horseshoe Hill, about 2,410 ft, 13 miles north-northwest.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 44×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 9 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 8 mi of the line.
Shale, limestone. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.
Arkose. Age: Miocene, 5.3 to 23 million years old. About 4 mi of the line.

A raindrop that lands in Edmond reaches the Gulf of America by way of the North Fork Solomon, the Solomon, the Smoky Hill, the Kansas, the Missouri and the Mississippi: about 2,060 river miles.
Lakes on the way: Waconda Lake and Kirwin Reservoir.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Edmond; river miles along the main stem, rounded.
Edmond has a hot-summer humid continental climate. Summer afternoons average 92° in July; winter nights fall to about 16° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 23 inches of water.
On November 14 Edmond normally reaches 56° and falls to 28°. The record high is 86°, in 1999; the record low −11°, in 1940. The most rain on this date, 0.50 in, fell in 1947.
Normals 1991–2020 and records since 1893 at Norton 9 SSE, 8 miles north, 280 ft higher. NOAA, through RCC-ACIS.
