18° on Nov. 17, 2014, the coldest reading for this week of the year since 1923. Next is 20° in 2019.
Lometa’s center stands about 1,490 ft above sea level. Within three miles the land runs from 1,330 ft to 1,620 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Knight Mountain, about 1,670 ft, 5 miles south-southeast.
Under the town center the state geologic map shows Walnut Clay (limestone, shale), from the Early Cretaceous, 100 to 145 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 32×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, claystone. Age: Early Cretaceous, 100 to 145 million years old. About 7 mi of the line.
Limestone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 5 mi of the line.
Claystone. Age: Early Cretaceous, 100 to 145 million years old. About 3 mi of the line.
Limestone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Dolostone, limestone. Age: Early Ordovician, 471 to 487 million years old. About 3 mi of the line.
Conglomerate, sandstone. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Lometa reaches the Gulf of America by way of Kirby Creek, Salt Creek and the Colorado: about 470 river miles.
Lakes on the way: Buchanan Lake, Lake Marble Falls and Lake Lyndon B Johnson.
320 miles of the trip are on the Colorado.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lometa; river miles along the main stem, rounded.
Lometa has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 33° in January. About 30 inches of rain fall in a normal year.
On November 14 Lometa normally reaches 67° and falls to 44°. The record high is 86°, in 1989; the record low 22°, in 2018. The most rain on this date, 3.11 in, fell in 1954.
Normals 1991–2020 and records since 1923 at Goldthwaite 1 WSW, 19 miles northwest. NOAA, through RCC-ACIS.
