3.25 inches of rain fell in two days, the most for this week of the year since records began in 1962. The next wettest, 2.85 inches, fell in 2003.
Falcon Heights’s center stands about 280 ft above sea level. Within three miles the land runs from 180 ft to 410 ft, a difference of 230 ft: rolling country.
Under the town center the state geologic map shows Yegua Formation (claystone, sandstone), from the Eocene, 34 to 56 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 52×. 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. Age: Late Eocene to Early Oligocene, 28 to 38 million years old. About 7 mi of the line.
Claystone, sandstone. Age: Eocene, 34 to 56 million years old. About 7 mi of the line.
Sandstone, claystone. Age: Eocene, 34 to 56 million years old. About 0.5 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.4 mi of the line.

A raindrop that lands in Falcon Heights reaches the Gulf of America by way of the Arroyo Morteros and the Rio Grande: about 270 river miles.

Falcon Heights has a hot semi-arid climate. Summer afternoons average 103° in August; winter nights fall to about 49° in January. About 20 inches of rain fall in a normal year.
On November 14 Falcon Heights normally reaches 80° and falls to 58°. The record high is 95°, in 1985; the record low 32°, in 2018. The most rain on this date, 1.59 in, fell in 2003.
