11° on Nov. 13, 2019, the coldest reading for this week of the year since 1878. Next is 12° in 1883.
Hilliard’s center stands about 940 ft above sea level. Within three miles the land runs from 830 ft to 970 ft, a difference of 140 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 62×. 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 13 mi of the line.
Limestone. Age: Devonian, 359 to 422 million years old. About 10 mi of the line.
Limestone. Age: Devonian, 359 to 422 million years old. About 1 mi of the line.
Shale, black-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 Hilliard reaches the Gulf of America by way of the Scioto, the Ohio and the Mississippi: about 1,730 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 Hilliard; river miles along the main stem, rounded.
Hilliard has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 22° in January. A normal year brings about 28 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Hilliard normally reaches 53° and falls to 35°. The record high is 74°, in 1909; the record low 12°, in 1986. The most rain on this date, 1.26 in, fell in 1897.
Normals 1991–2020 and records since 1878 from the Columbus Area threaded record (John Glenn International Airport, 15 miles east-southeast, 130 ft lower). NOAA, through RCC-ACIS.
