AIR MAIL

Where today’s air came from

The air arriving over Canton about 5,000 feet above the ground was over the open Pacific three days ago, and over the central Plains a day ago, about 2,630 miles back along its path. It came down from about 17,700 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 Rockies. 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 IN 2015 Nov. 17–18, 2015

The wettest two days this week has seen

3.22 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 2.58 inches, fell in 2009.

THE GROUND

What Canton stands on

Canton’s center stands about 510 ft above sea level. Within three miles the land runs from 470 ft to 650 ft, a difference of 180 ft: gently rolling country.

Under the town center the state geologic map shows Osagean Series (limestone), from the Carboniferous, 324 to 359 million years old.

The section below crosses 7 rock units mapped at the surface.
