76° on Nov. 11, 2012, the hottest reading for this week of the year since 1893. Next is 74° in 1999.
Newell’s center stands about 1,270 ft above sea level. Within three miles the land runs from 1,240 ft to 1,300 ft, a difference of 60 ft: nearly flat ground.
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.
Sandstone, shale. Age: Early Cretaceous to Late Cretaceous, 94 to 113 million years old. About 18 mi of the line.
Limestone. Age: Early Mississippian to Middle Mississippian, 331 to 359 million years old. About 4 mi of the line.
Sedimentary-breccia, shale. Age: Late Cretaceous, 72 to 84 million years old. About 1 mi of the line.
Dolostone, limestone, siltstone. Age: Early Mississippian, 347 to 359 million years old. About 0.3 mi of the line.

A raindrop that lands in Newell reaches the Gulf of America by way of Prairie Creek, Cedar Creek, the North Raccoon, the Des Moines and the Mississippi: about 1,720 river miles.
Lake on the way: Roberts Creek.
1,330 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Newell; river miles along the main stem, rounded.
Newell has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 9° in January. About 34 inches of rain fall in a normal year.
On November 14 Newell normally reaches 45° and falls to 27°. The record high is 70°, in 2001; the record low −9°, in 1940. The most rain on this date, 0.88 in, fell in 1902.
Normals 1991–2020 and records since 1893 at Storm Lake, 10 miles west-northwest, 170 ft higher. NOAA, through RCC-ACIS.
