4° on Nov. 12, 2019, the coldest reading for this week of the year since 1897. Next is 5° in 1933.
Coldwater’s center stands about 970 ft above sea level. Within three miles the land runs from 920 ft to 1,060 ft, a difference of 140 ft: gently rolling country.
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.
Shale. Age: Carboniferous, 324 to 359 million years old. About 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Coldwater reaches Lake Michigan by way of the Sauk, the Coldwater and the Saint Joseph: about 170 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Coldwater; river miles along the main stem, rounded.
Coldwater has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 16° in January. A normal year brings about 43 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Coldwater normally reaches 47° and falls to 31°. The record high is 69°, in 1902; the record low 8°, in 2019. The most rain on this date, 0.96 in, fell in 1957.
