74° on Nov. 11, 2020, the hottest reading for this week of the year since 1950. Next is 70° in 1964.
Roseville’s center stands about 620 ft above sea level. Within three miles the land runs from 580 ft to 630 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Antrim Shale (black-shale), from the Late Devonian, 359 to 384 million years old.
The section below crosses 5 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.
Black-shale. Age: Late Devonian, 359 to 384 million years old. About 11 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Sandstone. Age: Late Devonian, 359 to 384 million years old. About 1 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 1 mi of the line.
Black-shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 0.9 mi of the line.

A raindrop that lands in Roseville reaches Lake St. Clair by way of the Sweeney Drain, the Harrington Drain and the Clinton: about 15 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 Roseville; river miles along the main stem, rounded.
Roseville has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 17° in January. A normal year brings about 28 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Roseville normally reaches 48° and falls to 32°. The record high is 68°, in 1989; the record low 10°, in 2019. The most rain on this date, 1.10 in, fell in 1972.
Normals 1991–2020 and records since 1950 at Grosse Pointe Farms, 7 miles south-southeast. NOAA, through RCC-ACIS.
