73° on Nov. 16, 1953, the hottest reading for this week of the year since 1895. Next is 72° in 2012.
Warsaw’s center stands about 1,130 ft above sea level. Within three miles the land runs from 910 ft to 1,180 ft, a difference of 270 ft: rolling country.
Under the town center the state geologic map shows Upper Ordovician (limestone, dolostone), from the Late Ordovician, 445 to 459 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 41×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 13 mi of the line.
Limestone, dolostone. Age: Late Ordovician, 445 to 459 million years old. About 8 mi of the line.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Warsaw reaches the Gulf of America by way of the Little Cannon, the Cannon and the Mississippi: about 1,810 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Warsaw; river miles along the main stem, rounded.
Warsaw has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 4° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Warsaw normally reaches 43° and falls to 24°. The record high is 70°, in 1990; the record low −5°, in 1959. The most rain on this date, 0.90 in, fell in 1909.
Normals 1991–2020 and records since 1895 at Zumbrota, 17 miles east-southeast, 150 ft lower. NOAA, through RCC-ACIS.
