85° on Nov. 11, 2020, the hottest reading for this week of the year since 1955. Next is 82° in 1993.
Mascot’s center stands about 880 ft above sea level. Within three miles the land runs from 830 ft to 1,370 ft, a difference of 540 ft: hilly country. The highest named summit within 15 miles is Donehew Head, about 2,180 ft, 11 miles north-northeast.
Under the town center the state geologic map shows Newala Formation, including Mascot Dolomite and Kingsport Formation (dolostone), from the Ordovician, 445 to 487 million years old.
The section below crosses 18 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 18×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Mascot reaches the Gulf of America by way of Roseberry Creek, the Holston, the Tennessee, the Ohio and the Mississippi: about 1,670 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings Lake.
970 miles of the trip are on the Mississippi.

Mascot has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 27° in January. About 49 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Mascot normally reaches 62° and falls to 36°. The record high is 82°, in 1993; the record low 16°, in 1969. The most rain on this date, 0.48 in, fell in 1998.
Normals 1991–2020 and records since 1955 at Sevierville, 12 miles southeast. NOAA, through RCC-ACIS.
