4° on Nov. 13, 2019, the coldest reading for this week of the year since 1897. Next is 6° in 1959.
Yorkshire’s center stands about 980 ft above sea level. Within three miles the land runs from 950 ft to 1,040 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Lockport Dolomite (dolostone), from the Silurian, 425 to 445 million years old.
The section below crosses 4 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. Age: Silurian, 425 to 445 million years old. About 18 mi of the line.
Shale, dolostone, limestone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.
Dolostone. Age: Silurian, 422 to 445 million years old. About 1 mi of the line.
Dolostone, limestone, shale. Age: Silurian, 422 to 445 million years old. About 0.9 mi of the line.

A raindrop that lands in Yorkshire reaches the Gulf of America by way of Mile Creek, Loramie Creek, the Great Miami, the Ohio and the Mississippi: about 1,600 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Yorkshire; river miles along the main stem, rounded.
Yorkshire has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 19° in January. A normal year brings about 29 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Yorkshire normally reaches 51° and falls to 34°. The record high is 71°, in 1956; the record low 12°, in 1986. The most rain on this date, 2.49 in, fell in 1993.
Normals 1991–2020 and records since 1897 at Celina 3 NE, 17 miles north, 110 ft lower. NOAA, through RCC-ACIS.
