4° on Nov. 13, 2019, the coldest reading for this week of the year since 1897. Next is 6° in 1959.
Celina’s center stands about 880 ft above sea level. Within three miles the land runs from 850 ft to 910 ft, a difference of 60 ft: gently rolling country.
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, 422 to 445 million years old. About 15 mi of the line.
Dolostone. Age: Silurian, 428 to 445 million years old. About 6 mi of the line.
Dolostone. Age: Silurian, 425 to 445 million years old. About 3 mi of the line.
Shale, dolostone, limestone. Age: Ordovician, 445 to 487 million years old. About 0.7 mi of the line.

Celina straddles the St. Lawrence Divide. Rain on the southwest side runs to the Gulf of America; most of the rest goes to Lake Erie.
From the center of town, a raindrop reaches Lake Erie by way of Twelvemile Creek, the Saint Marys and the Maumee: about 210 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic. One that lands on the southwest side reaches the Gulf of America by way of Beaver Creek, the Wabash, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,570 river miles.
140 miles of the trip are on the Maumee.

Celina 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 Celina 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, 2 miles northeast. NOAA, through RCC-ACIS.
