76° on Nov. 14, 1994, the hottest reading for this week of the year since 1943. Next is 75° in 1949.
Kittanning’s center stands about 1,430 ft above sea level. Within three miles the land runs from 1,020 ft to 1,530 ft, a difference of 510 ft: hilly country. The highest named summit within 15 miles is Watts Hill, about 1,610 ft, 14 miles southeast.
Under the town center the state geologic map shows Glenshaw Formation (shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 24×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Carboniferous, 299 to 324 million years old. About 21 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.

A raindrop that lands in Kittanning reaches the Gulf of America by way of North Branch Cherry Run, Cherry Run, Crooked Creek, the Allegheny, the Ohio and the Mississippi: about 2,010 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Kittanning; river miles along the main stem, rounded.
Kittanning has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 17° in January. About 44 inches of rain fall in a normal year.
On November 14 Kittanning normally reaches 52° and falls to 30°. The record high is 76°, in 1994; the record low 9°, in 1986. The most rain on this date, 0.75 in, fell in 2007.
