25° on Nov. 14, 2018, the coldest reading for this week of the year since 1983. Next is 30° in 2019.
Ames’s center stands about 80 ft above sea level. Within three miles the land runs from 20 ft to 100 ft, a difference of 80 ft: gently rolling country.
The section below crosses 5 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.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 9 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 8 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

Ames has a humid subtropical climate. Summer afternoons average 92° in August; winter nights fall to about 41° in January. About 65 inches of rain fall in a normal year.
On November 14 Ames normally reaches 72° and falls to 50°. The record high is 85°, in 2005; the record low 25°, in 2018. The most rain on this date, 2.70 in, fell in 1998.
