85° on Nov. 11, 1989, the hottest reading for this week of the year since 1874. Next is 83° in 2016.
Bridgeton’s center stands about 580 ft above sea level. Within three miles the land runs from 430 ft to 620 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Marmaton Group (limestone, shale), from the Carboniferous, 299 to 324 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.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 11 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Shale, sandstone, siltstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.6 mi of the line.

A raindrop that lands in Bridgeton reaches the Gulf of America by way of Cowmire Creek, the Missouri and the Mississippi: about 1,200 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bridgeton; river miles along the main stem, rounded.
Bridgeton has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 24° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Bridgeton normally reaches 56° and falls to 38°. The record high is 81°, in 1971; the record low 13°, in 1940. The most rain on this date, 1.86 in, fell in 1993.
Normals 1991–2020 and records since 1874 from the St Louis Area threaded record (St Louis Lambert International Airport, 2 miles east-southeast). NOAA, through RCC-ACIS.
