20° on Nov. 12, 2019, the coldest reading for this week of the year since 1940. Next is 22° in 2014.
Midlothian’s center stands about 760 ft above sea level. Within three miles the land runs from 580 ft to 820 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Austin Chalk (marlstone, chalk), from the Late Cretaceous, 66 to 100 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 52×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Marlstone, chalk. Age: Late Cretaceous, 66 to 100 million years old. About 15 mi of the line.
Black-shale, siltstone. Age: Late Cretaceous, 66 to 100 million years old. About 6 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Midlothian reaches Galveston Bay and the Gulf of America by way of Waxahachie Creek, Chambers Creek, Richland Creek and the Trinity: about 420 river miles.
Lakes on the way: Woodlands Golf Course Lake and Bardwell Lake.
140 miles of the trip are on the Trinity.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Midlothian; river miles along the main stem, rounded.
Midlothian has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 36° in January. About 41 inches of rain fall in a normal year.
On November 14 Midlothian normally reaches 68° and falls to 45°. The record high is 89°, in 1989; the record low 25°, in 2018. The most rain on this date, 1.32 in, fell in 1994.
Normals 1991–2020 and records since 1940 at Ferris, 20 miles east, 290 ft lower. NOAA, through RCC-ACIS.
