AIR MAIL

Where today’s air came from

The air arriving over Baylis about 5,000 feet above the ground was over British Columbia three days ago, and over the central Plains a day ago, about 2,400 miles back along its path. It came down from about 11,700 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the northern Plains. It has stayed over land, which is why it feels dry. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THIS WEEK IN 2009 Nov. 16–17, 2009

The wettest two days this week has seen

4.38 inches of rain fell in two days, the most for this week of the year since records began in 1992. The next wettest, 3.15 inches, fell in 2015.

THE GROUND

What Baylis stands on

Baylis’s center stands about 860 ft above sea level. Within three miles the land runs from 690 ft to 860 ft, a difference of 170 ft: gently rolling country.

Under the town center the state geologic map shows Baylis Formation (sandstone), from the Late Cretaceous, 72 to 84 million years old.

The section below crosses 4 rock units mapped at the surface.
