6.52 inches of rain fell in two days, the most for this week of the year since records began in 1897. The next wettest, 5.13 inches, fell in 2003.
Montgomery’s center stands about 310 ft above sea level. Within three miles the land runs from 200 ft to 370 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Fleming Formation (clay, sandstone), from the Miocene, 5.3 to 23 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 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.
Coarse-detrital, fine-detrital. Age: Pliocene, 2.6 to 5.3 million years old. About 18 mi of the line.
Clay, sandstone. Age: Miocene, 5.3 to 23 million years old. About 5 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Silt, sand, clay. Age: Pleistocene, less than 2.6 million years old. About 0.6 mi of the line.

A raindrop that lands in Montgomery reaches Galveston Bay and the Gulf of America by way of Town Creek, the West Fork San Jacinto, the San Jacinto and Buffalo Bayou: about 90 river miles.
Lakes on the way: Lake Conroe and Lake Houston.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Montgomery; river miles along the main stem, rounded.
Montgomery has a humid subtropical climate. Summer afternoons average 96° in August; winter nights fall to about 42° in January. About 51 inches of rain fall in a normal year.
On November 14 Montgomery normally reaches 72° and falls to 51°. The record high is 89°, in 1959; the record low 21°, in 1982. The most rain on this date, 1.46 in, fell in 1920.
Normals 1991–2020 and records since 1897 at Conroe, 13 miles east-southeast. NOAA, through RCC-ACIS.
