AIR MAIL

Where today’s air came from

The air arriving over Boiling Springs about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,630 miles back along its path. It came down from about 11,300 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; 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, SIX YEARS AGO Nov. 11, 2020

The hottest this week has been

76° on Nov. 11, 2020, the hottest reading for this week of the year since 1840. Next is 74° in 2009.

THE GROUND

What Boiling Springs stands on

Boiling Springs’s center stands about 500 ft above sea level. Within three miles the land runs from 460 ft to 1,120 ft, a difference of 660 ft: hilly country. The highest named summit within 15 miles is Chimney Rocks, about 1,600 ft, 14 miles west-southwest.

Under the town center the state geologic map shows Elbrook Formation (limestone), from the Cambrian, 487 to 542 million years old.
