89° on Nov. 14, 1989, the hottest reading for this week of the year since 1898. Next is 89° in 2025.
Colleyville’s center stands about 610 ft above sea level. Within three miles the land runs from 560 ft to 700 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Blue Mound, about 840 ft, 12 miles west-northwest.
Under the town center the state geologic map shows Woodbine Formation (sandstone-mudstone), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 56×. 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-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 13 mi of the line.
Marlstone, limestone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 5 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Black-shale, siltstone. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.
Claystone. Age: Early Cretaceous, 100 to 145 million years old. About 0.7 mi of the line.

A raindrop that lands in Colleyville reaches Galveston Bay and the Gulf of America by way of Little Bear Creek, Bear Creek and the Trinity: about 480 river miles.
Lake on the way: Woodlands Golf Course Lake.
270 miles of the trip are on the Trinity.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Colleyville; river miles along the main stem, rounded.
Colleyville has a humid subtropical climate. Summer afternoons average 96° in July; winter nights fall to about 36° in January. About 37 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Colleyville normally reaches 67° and falls to 47°. The record high is 89°, in 1989; the record low 21°, in 1916. The most rain on this date, 1.82 in, fell in 1994.
Normals 1991–2020 and records since 1898 from the Dallas-Fort Worth Area threaded record (Dal-Ftw Wscmo Airport, 8 miles east). NOAA, through RCC-ACIS.
