4.54 inches of rain fell in two days, the most for this week of the year since records began in 1890. The next wettest, 2.92 inches, fell in 1978.
Pana’s center stands about 700 ft above sea level. Within three miles the land runs from 650 ft to 730 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Mattoon Formation (shale), from the Late Pennsylvanian, 304 to 307 million years old.
The section below crosses 2 rock units mapped at the surface.

Shale. Age: Late Pennsylvanian, 304 to 307 million years old. About 20 mi of the line.
Shale, sandstone, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 4 mi of the line.

A raindrop that lands in Pana reaches the Gulf of America by way of Lake Fork, Flat Branch, the South Fork Sangamon, the Sangamon, the Illinois and the Mississippi: about 1,460 river miles.
1,190 miles of the trip are on the Mississippi.

Pana has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 19° in January. A normal year brings about 14 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Pana normally reaches 54° and falls to 34°. The record high is 78°, in 1999; the record low 9°, in 1900. The most rain on this date, 2.74 in, fell in 1978.
