AIR MAIL

Where today’s air came from

The air arriving over Hostetter about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,580 miles back along its path. It came down from about 9,800 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the open Pacific. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THIS WEEK, FOUR YEARS AGO Nov. 12–13, 2022

The wettest two days this week has seen

4.45 inches of rain fell in two days, the most for this week of the year since records began in 1980. The next wettest, 2.62 inches, fell in 2015.

THE GROUND

What Hostetter stands on

Hostetter’s center stands about 1,140 ft above sea level. Within three miles the land runs from 1,000 ft to 2,130 ft, a difference of 1,130 ft: steep hill country. The highest named summit within 15 miles is Bald Knob, about 2,960 ft, 15 miles southeast.

Under the town center the state geologic map shows Monongahela Group (limestone, shale, sandstone), from the Carboniferous, 299 to 324 million years old.

The section below crosses 5 rock units mapped at the surface.
