3.20 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 2.72 inches, fell in 1951.
Kirkland’s center stands about 780 ft above sea level. Within three miles the land runs from 750 ft to 890 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Galena Group (Trenton Limestone) (dolostone, limestone), from the Late Ordovician, 447 to 459 million 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.
Dolostone, limestone. Age: Late Ordovician, 447 to 459 million years old. About 19 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 4 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 454 to 459 million years old. About 0.8 mi of the line.
Sandstone, limestone, dolostone. Age: Middle Ordovician to Late Ordovician, 454 to 468 million years old. About 0.5 mi of the line.

A raindrop that lands in Kirkland reaches the Gulf of America by way of Bull Run, the South Branch Kishwaukee, the Kishwaukee, the Rock River and the Mississippi: about 1,610 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Kirkland; river miles along the main stem, rounded.
Kirkland has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 15° in January. A normal year brings about 37 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Kirkland normally reaches 48° and falls to 31°. The record high is 73°, in 1971; the record low 4°, in 1959. The most rain on this date, 1.19 in, fell in 1926.
