24° on Nov. 13, 2013, the coldest reading for this week of the year since 1980. Next is 24° in 2018.
Weir’s center stands about 680 ft above sea level. Within three miles the land runs from 610 ft to 830 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Rabbit Hill, about 950 ft, 9 miles southwest.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 43×. 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. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Limestone, dolostone. Age: Early Cretaceous, 100 to 145 million years old. About 5 mi of the line.
Marlstone, chalk. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Black-shale, siltstone. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 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. 4 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 Weir reaches the Gulf of America by way of the San Gabriel, the Little River and the Brazos: about 420 river miles.
Lake on the way: Granger Lake.
320 miles of the trip are on the Brazos.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Weir; river miles along the main stem, rounded.
Weir has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 36° in January. About 37 inches of rain fall in a normal year.
On November 14 Weir normally reaches 70° and falls to 47°. The record high is 86°, in 2006; the record low 26°, in 2018. The most rain on this date, 0.41 in, fell in 1998.
Normals 1991–2020 and records since 1980 at Georgetown Lake, 8 miles west, 190 ft higher. NOAA, through RCC-ACIS.
