3.01 inches of rain fell in two days, the most for this week of the year since records began in 1887. The next wettest, 2.14 inches, fell in 2011.
Suffield’s center stands about 1,190 ft above sea level. Within three miles the land runs from 1,080 ft to 1,260 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Allegheny and Pottsville Groups, Undivided (shale, siltstone), 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 60×. 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, siltstone. Age: Carboniferous, 299 to 324 million years old. About 22 mi of the line.
Shale, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 2 mi of the line.
Sandstone, shale. Age: Devonian, 359 to 422 million years old. About 0.4 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 Suffield reaches Lake Erie by way of Potter Creek, Breakneck Creek and the Cuyahoga: about 70 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
55 miles of the trip are on the Cuyahoga.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Suffield; river miles along the main stem, rounded.
Suffield has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 20° in January. A normal year brings about 47 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Suffield normally reaches 51° and falls to 35°. The record high is 73°, in 1909; the record low 11°, in 1986. The most rain on this date, 2.13 in, fell in 2011.
