85° on Nov. 15, 2025, the hottest reading for this week of the year since 1935. Next is 84° in 1955.
Loraine’s center stands about 2,280 ft above sea level. Within three miles the land runs from 2,190 ft to 2,430 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is Bench Mountain, about 2,600 ft, 11 miles southeast.
Under the town center the state geologic map shows Dockum Group, undivided (shale), from the Middle Triassic to Late Triassic, 208 to 247 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 48×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Middle Triassic to Late Triassic, 208 to 247 million years old. About 13 mi of the line.
Sand. Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 10 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 113 million years old. About 0.3 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.3 mi of the line.
Sandstone, claystone. Age: Early Cretaceous, 100 to 145 million years old. About 0.3 mi of the line.

A raindrop that lands in Loraine reaches the Gulf of America by way of North Fork Champion Creek, Champion Creek and the Colorado: about 780 river miles.
Lakes on the way: Buchanan Lake, Lake Marble Falls, E V Spence Reservoir 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 Loraine; river miles along the main stem, rounded.
Loraine has a humid subtropical climate. Summer afternoons average 95° in July; winter nights fall to about 31° in January. About 21 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Loraine normally reaches 65° and falls to 41°. The record high is 83°, in 1989; the record low 12°, in 1976. The most rain on this date, 0.90 in, fell in 1954.
Normals 1991–2020 and records since 1935 at Roscoe, 11 miles east-northeast, 100 ft higher. NOAA, through RCC-ACIS.
