74° on Nov. 11, 2020, the hottest reading for this week of the year since 1964. Next is 70° in 1964.
Barr’s center stands about 1,900 ft above sea level. Within three miles the land runs from 1,560 ft to 2,080 ft, a difference of 520 ft: hilly country.
Under the town center the state geologic map shows Casselman Formation (shale, clastic), from the Carboniferous, 299 to 324 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 20×. 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 19 mi of the line.
Shale, clastic. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.

Barr straddles the Eastern Continental Divide. Rain on the northeast side runs to Chesapeake Bay and the Atlantic Ocean; most of the rest goes to the Gulf of America.
From the center of town, a raindrop reaches the Gulf of America by way of North Branch Blacklick Creek, Blacklick Creek, the Conemaugh, the Kiskiminetas, the Allegheny, the Ohio and the Mississippi: about 2,060 river miles. One that lands on the northeast side reaches Chesapeake Bay and the Atlantic Ocean by way of Browns Run, the West Branch Susquehanna and the Susquehanna: about 370 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 Barr; river miles along the main stem, rounded.
Barr has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 16° in January. A normal year brings about 80 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Barr normally reaches 48° and falls to 29°. The record high is 69°, in 1994; the record low 5°, in 1986. The most rain on this date, 0.74 in, fell in 1993.
Normals 1991–2020 and records since 1964 at Ebensburg Sewage Plant, 11 miles south-southeast. NOAA, through RCC-ACIS.
