−7° on Nov. 11, 1995, the coldest reading for this week of the year since 1981. Next is 3° in 1996.
Willernie’s center stands about 970 ft above sea level. Within three miles the land runs from 910 ft to 1,070 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Middle and Upper Ordovician (shale, limestone, sandstone), from the Middle Ordovician to Late Ordovician, 445 to 471 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 44×. 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 11 mi of the line.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 9 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 2 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 Willernie reaches the Gulf of America by way of Clearwater Creek, Coon Creek and the Mississippi: about 1,880 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Willernie; river miles along the main stem, rounded.
Willernie has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 8° in January. About 33 inches of rain fall in a normal year.
On November 14 Willernie normally reaches 43° and falls to 29°. The record high is 71°, in 1990; the record low 4°, in 1996. The most rain on this date, 0.13 in, fell in 1983.
Normals 1991–2020 and records since 1981 at Vadnais Lake, 7 miles west. NOAA, through RCC-ACIS.
