Plano’s center stands about 610 ft above sea level. Within three miles the land runs from 470 ft to 680 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Pilot Knob, about 950 ft, 15 miles west-southwest.
Under the town center the state geologic map shows Ste. Genevieve and St. Louis Limestones, undivided, from the Carboniferous, 324 to 359 million years old.
The section below crosses 3 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.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 19 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 5 mi of the line.

A raindrop that lands in Plano reaches the Gulf of America by way of Drakes Creek, the Barren, the Green River, the Ohio and the Mississippi: about 1,380 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Plano; river miles along the main stem, rounded.
Plano has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 28° in January. A normal year brings about 8 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Plano normally reaches 60° and falls to 38°. The record high is 80°, in 1964; the record low 15°, in 1986. The most rain on this date, 1.13 in, fell in 1993.
Normals 1991–2020 and records since 1893 at Bowling Green Warren County Airport, 6 miles north. NOAA, through RCC-ACIS.
