76° on Nov. 11, 2022, the hottest reading for this week of the year since 1895. Next is 75° in 1911.
Erie’s center stands about 590 ft above sea level. Within three miles the land runs from 570 ft to 630 ft, a difference of 60 ft: nearly flat ground.
Under the town center the state geologic map shows Silurian System undivided (dolostone, limestone), from the Silurian, 422 to 445 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 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, limestone. Age: Silurian, 422 to 445 million years old. About 20 mi of the line.
Shale, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Erie reaches the Gulf of America by way of the Rock River and the Mississippi: about 1,490 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Erie; river miles along the main stem, rounded.
Erie has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 12° in January. A normal year brings about 32 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Erie normally reaches 48° and falls to 29°. The record high is 75°, in 1999; the record low 3°, in 1996. The most rain on this date, 1.25 in, fell in 1926.
Normals 1991–2020 and records since 1895 at Morrison, 11 miles north-northeast. NOAA, through RCC-ACIS.
