74° on Nov. 14, 1990, the hottest reading for this week of the year since 1911. Next is 74° in 1999.
Brady’s center stands about 3,530 ft above sea level. Within three miles the land runs from 3,430 ft to 3,610 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Sam George Hill, about 3,970 ft, 14 miles northwest.
Under the town center the state geologic map shows Kevin Member of Marias River Formation (shale, limestone, dolostone), from the Late Cretaceous, 84 to 90 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 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, limestone, dolostone. Age: Late Cretaceous, 84 to 90 million years old. About 21 mi of the line.
Age: Late Miocene to Holocene, less than 7.2 million years old. About 2 mi of the line.
Sandstone, siltstone, shale. Age: Late Cretaceous, 72 to 87 million years old. About 1 mi of the line.

A raindrop that lands in Brady reaches the Gulf of America by way of the Marias, the Missouri and the Mississippi: about 3,360 river miles.
Lakes on the way: Lake Oahe, Lake Sakakawea, Lake Fort Peck and Lake Sharpe.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Brady; river miles along the main stem, rounded.
Brady has a cold semi-arid climate. Summer afternoons average 82° in July; winter nights fall to about 11° in January. A normal year brings about 47 inches of snow; with the rain, that comes to about 13 inches of water.
On November 14 Brady normally reaches 44° and falls to 21°. The record high is 74°, in 1990; the record low −16°, in 2014. The most rain on this date, 0.49 in, fell in 1988.
Normals 1991–2020 and records since 1911 at Conrad, 11 miles north-northwest. NOAA, through RCC-ACIS.
