16° on Nov. 13, 2019, the coldest reading for this week of the year since 1948. Next is 20° in 1997.
Itta Bena’s center stands about 130 ft above sea level. Within three miles the land runs from 110 ft to 180 ft, a difference of 70 ft: gently rolling country. The highest named summit within 15 miles is Millers Hill, about 400 ft, 15 miles east-southeast.
Under the town center the state geologic map shows Alluvium (fine-detrital, coarse-detrital), from the Holocene, less than 12,000 years old.
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 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Itta Bena reaches the Gulf of America by way of Gin Bayou, the Big Sunflower, the Yazoo and the Mississippi: about 620 river miles.
450 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Itta Bena; river miles along the main stem, rounded.
Itta Bena has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 35° in January. About 52 inches of rain fall in a normal year.
On November 14 Itta Bena normally reaches 66° and falls to 42°. The record high is 86°, in 1955; the record low 21°, in 2014. The most rain on this date, 2.67 in, fell in 1998.
Normals 1991–2020 and records since 1948 from the Greenwood Area threaded record (Greenwood Leflore Airport, 14 miles east). NOAA, through RCC-ACIS.
