77° on Nov. 11, 1964, the hottest reading for this week of the year since 1893. Next is 76° in 1999.
Norway’s center stands about 800 ft above sea level. Within three miles the land runs from 770 ft to 910 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Cedar Valley Group (limestone, dolostone), from the Middle Devonian to Late Devonian, 374 to 388 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 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, dolostone. Age: Late Devonian, 374 to 384 million years old. About 9 mi of the line.
Shale, sandstone, siltstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 7 mi of the line.
Limestone, dolostone. Age: Middle Devonian to Late Devonian, 374 to 388 million years old. About 4 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 374 million years old. About 3 mi of the line.

A raindrop that lands in Norway reaches the Gulf of America by way of the Cedar River, the Iowa and the Mississippi: about 1,540 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Norway; river miles along the main stem, rounded.
Norway has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 11° in January. About 36 inches of rain fall in a normal year.
On November 14 Norway normally reaches 47° and falls to 28°. The record high is 75°, in 1964; the record low 0°, in 1959. The most rain on this date, 1.42 in, fell in 1956.
