74° on Nov. 16, 1993, the hottest reading for this week of the year since 1888. Next is 73° in 2020.
Storrs’s center stands about 630 ft above sea level. Within three miles the land runs from 280 ft to 730 ft, a difference of 450 ft: hilly country. The highest named summit within 15 miles is Burley Hill, about 1,320 ft, 15 miles north.
Under the town center the state geologic map shows Hebron Gneiss (schist, calc-silicate-rock), from the Neoproterozoic, 542 to 1,000 million years old.
The section below crosses 16 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 4 mi of the line.
Schist, calc-silicate-rock. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Schist. Age: Silurian to Devonian, 359 to 445 million years old. About 3 mi of the line.
Gneiss, amphibolite. Age: Early Ordovician to Middle Ordovician, 459 to 487 million years old. About 2 mi of the line.
Schist, gneiss. Age: Cambrian to Ordovician, 445 to 542 million years old. About 2 mi of the line.
Gneiss. Age: Middle Ordovician, 459 to 471 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 10 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Storrs reaches Long Island Sound and the Atlantic Ocean by way of the Willimantic, the Shetucket and the Thames: about 45 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Storrs; river miles along the main stem, rounded.
Storrs has a hot-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 19° in January. A normal year brings about 39 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Storrs normally reaches 51° and falls to 34°. The record high is 67°, in 1902; the record low 10°, in 1905. The most rain on this date, 2.21 in, fell in 1937.
