86° on Nov. 12, 2016, the hottest reading for this week of the year since 1940. Next is 82° in 1964.
Patterson’s center stands about 200 ft above sea level. Within three miles the land runs from 190 ft to 260 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Terrace deposits (coarse-detrital, fine-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 4 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.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 17 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Patterson reaches the Gulf of America by way of the Cache, the White River and the Mississippi: about 790 river miles.
620 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Patterson; river miles along the main stem, rounded.
Patterson has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 31° in January. About 51 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Patterson normally reaches 60° and falls to 41°. The record high is 81°, in 1964; the record low 18°, in 1986. The most rain on this date, 2.67 in, fell in 1959.
Normals 1991–2020 and records since 1940 at Beedeville 4 NE, 17 miles northeast. NOAA, through RCC-ACIS.
