3.79 inches of rain fell in two days, the most for this week of the year since records began in 1934. The next wettest, 1.97 inches, fell in 1961.
Riverside’s center stands about 770 ft above sea level. Within three miles the land runs from 720 ft to 1,000 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Nebo Hill, about 950 ft, 14 miles east.
Under the town center the state geologic map shows Kansas City Group (limestone, shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 53×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 11 mi of the line.
Shale, limestone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.6 mi of the line.

A raindrop that lands in Riverside reaches the Gulf of America by way of Line Creek, the Missouri and the Mississippi: about 1,530 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Riverside; river miles along the main stem, rounded.
Riverside has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 22° in January. A normal year brings about 11 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Riverside normally reaches 55° and falls to 37°. The record high is 81°, in 1964; the record low 10°, in 1940. The most rain on this date, 1.52 in, fell in 1968.
Normals 1991–2020 and records since 1934 at Kansas City Downtown Airport, 4 miles south-southeast. NOAA, through RCC-ACIS.
