11° on Nov. 13, 2019, the coldest reading for this week of the year since 1897. Next is 12° in 1916.
Williford’s center stands about 340 ft above sea level. Within three miles the land runs from 300 ft to 660 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Britton Hill, about 820 ft, 13 miles north-northwest.
Under the town center the state geologic map shows Cotter and Jefferson City Dolomites (dolostone), from the Early Ordovician, 471 to 487 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 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 16 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 7 mi of the line.
Sandstone, dolostone. Age: Middle Ordovician, 459 to 471 million years old. About 2 mi of the line.

A raindrop that lands in Williford reaches the Gulf of America by way of the Spring, the Black River, the White River and the Mississippi: about 980 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 Williford; river miles along the main stem, rounded.
Williford has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 26° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Williford normally reaches 59° and falls to 38°. The record high is 78°, in 1999; the record low 11°, in 2019. The most rain on this date, 0.85 in, fell in 1915.
Normals 1991–2020 and records since 1897 at Hardy, 8 miles west. NOAA, through RCC-ACIS.
