71° on Nov. 11, 1964, the hottest reading for this week of the year since 1948. Next is 71° in 1999.
Leopolis’s center stands about 910 ft above sea level. Within three miles the land runs from 850 ft to 1,130 ft, a difference of 280 ft: rolling country.
Under the town center the state geologic map shows Wolf River batholith; Red River Granite, from the Mesoproterozoic, 1 to 1.6 billion 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 49×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 17 mi of the line.
Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 8 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 0.1 mi of the line.

A raindrop that lands in Leopolis reaches Lake Michigan by way of the North Branch Embarrass, the Embarrass, the Wolf River and the Fox River: about 180 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lakes on the way: Lake Winnebago 6124, Lake Winneconne and Lake Butte des Morts.
55 miles of the trip are on the Embarrass.

Leopolis has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 7° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Leopolis normally reaches 44° and falls to 26°. The record high is 65°, in 1958; the record low 0°, in 1986. The most rain on this date, 0.45 in, fell in 1957.
Normals 1991–2020 and records since 1948 at Clintonville, 11 miles south-southeast, 110 ft lower. NOAA, through RCC-ACIS.
