80° on Nov. 14, 1999, the hottest reading for this week of the year since 1898. Next is 75° in 2012.
Verona’s center stands about 1,090 ft above sea level. Within three miles the land runs from 1,030 ft to 1,110 ft, a difference of 80 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 3 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.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 9 mi of the line.
Limestone, dolostone. Age: Late Ordovician, 445 to 459 million years old. About 9 mi of the line.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 6 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 Verona reaches the Gulf of America by way of South Creek, the Blue Earth, the Minnesota and the Mississippi: about 2,020 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Verona; river miles along the main stem, rounded.
Verona has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 6° in January. A normal year brings about 47 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Verona normally reaches 43° and falls to 26°. The record high is 80°, in 1999; the record low −7°, in 1940. The most rain on this date, 1.26 in, fell in 1909.
Normals 1991–2020 and records since 1898 at Winnebago, 4 miles north-northeast. NOAA, through RCC-ACIS.
