5.21 inches of rain fell in two days, the most for this week of the year since records began in 1945. The next wettest, 3.95 inches, fell in 2020.
Lexington Park’s center stands about 120 ft above sea level. Within three miles the land runs from 10 ft to 160 ft, a difference of 150 ft: gently rolling country. Open water lies within three miles.
Under the town center the state geologic map shows Upland Deposits (Western Shore) (gravel, sand), from the Pleistocene, less than 2.6 million years old.
The section below crosses 3 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.
Gravel, sand. Age: Pleistocene, less than 2.6 million years old. About 9 mi of the line.
Clay, sand. Age: Miocene, 5.3 to 23 million years old. About 7 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Lexington Park reaches Chesapeake Bay and the Atlantic Ocean by way of Penbrook Run, Eastern Branch, the Saint Marys and the Potomac: about 25 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lexington Park; river miles along the main stem, rounded.
Lexington Park has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 29° in January. A normal year brings about 12 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Lexington Park normally reaches 59° and falls to 42°. The record high is 78°, in 1955; the record low 24°, in 2019. The most rain on this date, 1.44 in, fell in 1995.
Normals 1991–2020 and records since 1945 at Patuxent River Nas, 3 miles northeast. NOAA, through RCC-ACIS.
