The Osceola plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
82° on Nov. 13, 1999, the hottest reading for this week of the year since 1955. Next is 80° in 1958.
Osceola’s center stands about 760 ft above sea level. Within three miles the land runs from 700 ft to 890 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Spangler Hill, about 980 ft, 10 miles south-southwest.
Under the town center the state geologic map shows Osagean Series (limestone), from the Carboniferous, 324 to 359 million years old.
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 60×. 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, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 16 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 7 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.6 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 0.5 mi of the line.

A raindrop that lands in Osceola reaches the Gulf of America by way of the Osage, the Missouri and the Mississippi: about 1,520 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 Osceola; river miles along the main stem, rounded.
Osceola has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 21° in January. A normal year brings about 10 inches of snow; with the rain, that comes to about 43 inches of water.
On November 14 Osceola normally reaches 57° and falls to 35°. The record high is 79°, in 1964; the record low 10°, in 2018. The most rain on this date, 2.13 in, fell in 1985.
