75° on Nov. 16, 2001, the hottest reading for this week of the year since 1893. Next is 74° in 1953.
Lisbon’s center stands about 1,030 ft above sea level. Within three miles the land runs from 1,020 ft to 1,060 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Granitic orthogneiss and migmatite (orthogneiss, migmatite), from the Paleoarchean to Mesoarchean, 2.8 to 3.6 billion 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.
Orthogneiss, migmatite. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 11 mi of the line.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 10 mi of the line.
Gabbro, pyroxenite, diorite. Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 2 mi of the line.
Granitic. Age: Archean to Paleoproterozoic. About 1 mi of the line.

A raindrop that lands in Lisbon reaches the Gulf of America by way of the Minnesota and the Mississippi: about 2,100 river miles.
Lake on the way: Lake Pepin.
1,750 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lisbon; river miles along the main stem, rounded.
Lisbon has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 4° in January. A normal year brings about 51 inches of snow; with the rain, that comes to about 27 inches of water.
On November 14 Lisbon normally reaches 44° and falls to 25°. The record high is 72°, in 2025; the record low −10°, in 1940. The most rain on this date, 1.25 in, fell in 1927.
Normals 1991–2020 and records since 1893 at Milan 1 NW, 20 miles north-northwest. NOAA, through RCC-ACIS.
