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.
Farmersville’s center stands about 1,850 ft above sea level. Within three miles the land runs from 1,710 ft to 2,190 ft, a difference of 480 ft: hilly country. The highest named summit within 15 miles is Laidlaw Hill, about 2,330 ft, 10 miles southwest.
Under the town center the state geologic map shows Machias Formation (shale, siltstone, sandstone), from the Late Devonian, 359 to 384 million years old.

Farmersville straddles the St. Lawrence Divide. Rain on the northeast side runs to Lake Erie; most of the rest goes to the Gulf of America.
From the center of town, a raindrop reaches the Gulf of America by way of Johnson Creek, Olean Creek, the Allegheny, the Ohio and the Mississippi: about 2,230 river miles. One that lands on the northeast side reaches Lake Erie by way of Elton Creek and Cattaraugus Creek: about 65 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lake on the way: Allegheny Reservoir.
970 miles of the trip are on the Ohio.

Farmersville 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 Farmersville 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.
