3.60 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 2.76 inches, fell in 1913.
Winfield’s center stands about 540 ft above sea level. Within three miles the land runs from 430 ft to 690 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Tucker Knob, about 890 ft, 13 miles east.
Under the town center the state geologic map shows Holocene series (clay, silt, sand), from the Holocene, less than 12,000 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 38×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 13 mi of the line.
Limestone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 5 mi of the line.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
Limestone, sandstone. Age: Early Devonian to Late Devonian, 359 to 422 million years old. About 1 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 0.5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Winfield reaches the Gulf of America by way of McLean Creek, Bobs Creek and the Mississippi: about 1,210 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Winfield; river miles along the main stem, rounded.
Winfield has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 22° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Winfield normally reaches 56° and falls to 36°. The record high is 83°, in 1955; the record low 11°, in 1986. The most rain on this date, 2.21 in, fell in 1913.
Normals 1991–2020 and records since 1893 at St Charles Elm Point, 18 miles southeast. NOAA, through RCC-ACIS.
