22° on Nov. 13, 2019, the coldest reading for this week of the year since 1968. Next is 25° in 1969.
Leary’s center stands about 390 ft above sea level. Within three miles the land runs from 300 ft to 420 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Midway Group, undivided (clay, sand), from the Paleocene to Eocene, 34 to 66 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Mudstone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 5 mi of the line.
Clay, sand. Age: Paleocene to Eocene, 34 to 66 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.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 0.5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit 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 Leary reaches the Gulf of America by way of Jones Creek, Barkman Creek, McKinney Bayou, the Red River, the Atchafalaya and the Lower Atchafalaya: about 570 river miles.
420 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Leary; river miles along the main stem, rounded.
Leary has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 33° in January. About 52 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Leary normally reaches 65° and falls to 43°. The record high is 83°, in 2005; the record low 22°, in 2019. The most rain on this date, 1.92 in, fell in 1970.
Normals 1991–2020 and records since 1968 at Texarkana, 8 miles east-southeast. NOAA, through RCC-ACIS.
