74° on Nov. 11, 2020, the hottest reading for this week of the year since 1964. Next is 70° in 1964.
Elmora’s center stands about 1,680 ft above sea level. Within three miles the land runs from 1,510 ft to 2,210 ft, a difference of 700 ft: hilly country. The highest named summit within 15 miles is Pringle Hill, about 1,920 ft, 14 miles south.
Under the town center the state geologic map shows Allegheny Formation (sandstone), 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 18×. 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 15 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 9 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 0.4 mi of the line.

A raindrop that lands in Elmora reaches Chesapeake Bay and the Atlantic Ocean by way of the West Branch Susquehanna and the Susquehanna: about 370 river miles.
Lake on the way: Lake Aldred.
240 miles of the trip are on the West Branch Susquehanna.

Elmora 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 Elmora 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, 9 miles south, 260 ft higher. NOAA, through RCC-ACIS.
