73° on Nov. 14, 1999, the hottest reading for this week of the year since 1893. Next is 73° in 2012.
Randalia’s center stands about 1,120 ft above sea level. Within three miles the land runs from 1,050 ft to 1,180 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Cedar Valley Group (limestone, dolostone), from the Middle Devonian to Late Devonian, 374 to 388 million years old.
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 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Silurian, 440 to 445 million years old. About 8 mi of the line.
Limestone, dolostone. Age: Middle Devonian to Late Devonian, 374 to 388 million years old. About 7 mi of the line.
Shale, dolostone. Age: Late Ordovician, 447 to 454 million years old. About 6 mi of the line.
Dolostone. Age: Late Ordovician to Silurian, 434 to 447 million years old. About 4 mi of the line.

A raindrop that lands in Randalia reaches the Gulf of America by way of the Volga, the Turkey and the Mississippi: about 1,670 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Randalia; river miles along the main stem, rounded.
Randalia has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 6° in January. A normal year brings about 41 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Randalia normally reaches 45° and falls to 25°. The record high is 73°, in 1999; the record low −3°, in 1916. The most rain on this date, 1.68 in, fell in 1927.
Normals 1991–2020 and records since 1893 at Fayette, 3 miles east-northeast. NOAA, through RCC-ACIS.
