72° on Nov. 11, 1964, the hottest reading for this week of the year since 1944. Next is 71° in 1971.
Pleasant Prairie’s center stands about 700 ft above sea level. Within three miles the land runs from 670 ft to 760 ft, a difference of 90 ft: gently rolling country. The highest named summit within 15 miles is Gander Mountain, about 960 ft, 14 miles west-southwest.
Under the town center the state geologic map shows Silurian, undivided (dolostone), from the Silurian, 422 to 445 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 63×. 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: Silurian, 422 to 445 million years old. About 17 mi of the line.
Dolostone, limestone. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.

Pleasant Prairie straddles the St. Lawrence Divide. Rain on the east side runs to Lake Michigan; most of the rest goes to the Gulf of America.
From the center of town, a raindrop reaches the Gulf of America by way of the Des Plaines, the Illinois and the Mississippi: about 1,580 river miles. One that lands on the east side reaches Lake Michigan by way of Barnes Creek: about 2 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lake on the way: Peoria Lake.
1,190 miles of the trip are on the Mississippi.

Pleasant Prairie has a hot-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 17° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Pleasant Prairie normally reaches 48° and falls to 33°. The record high is 71°, in 1971; the record low 10°, in 1959. The most rain on this date, 1.09 in, fell in 1957.
Normals 1991–2020 and records since 1944 at Kenosha Wwtp, 6 miles east, 100 ft lower. NOAA, through RCC-ACIS.
