82° on Nov. 11, 1989, the hottest reading for this week of the year since 1906. Next is 81° in 1999.
Greeley’s center stands about 900 ft above sea level. Within three miles the land runs from 870 ft to 1,110 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Alluvium (sand, silt, clay), from the Pleistocene to Holocene, less than 2.6 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 60×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 12 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Shale, limestone. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.

A raindrop that lands in Greeley reaches the Gulf of America by way of Pottawatomie Creek, the Marais des Cygnes, the Osage, the Missouri and the Mississippi: about 1,700 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Greeley; river miles along the main stem, rounded.
Greeley has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 20° in January. A normal year brings about 13 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Greeley normally reaches 56° and falls to 34°. The record high is 79°, in 1964; the record low 8°, in 1959. The most rain on this date, 0.93 in, fell in 1909.
Normals 1991–2020 and records since 1906 at Garnett 1 E, 8 miles southwest. NOAA, through RCC-ACIS.
