3.14 inches of rain fell in two days, the most for this week of the year since records began in 1896. The next wettest, 2.23 inches, fell in 1965.
Arcade’s center stands about 1,490 ft above sea level. Within three miles the land runs from 1,400 ft to 1,940 ft, a difference of 540 ft: hilly country. The highest named summit within 15 miles is Bush Hill, about 2,210 ft, 11 miles south-southeast.
Under the town center the state geologic map shows Machias Formation (shale, siltstone, sandstone), from the Late Devonian, 359 to 384 million years old.
The section below crosses 3 rock units mapped at the surface.

A raindrop that lands in Arcade reaches Lake Erie by way of Cattaraugus Creek: about 60 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.

Arcade has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 13° in January. A normal year brings about 109 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Arcade normally reaches 47° and falls to 29°. The record high is 66°, in 1989; the record low −4°, in 1905. The most rain on this date, 1.04 in, fell in 1972.
