AIR MAIL

Where today’s air came from

The air arriving over Perry about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,480 miles back along its path. Near the ground the air came from British Columbia; at 10,000 feet, from the Gulf of Alaska. 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 1943. Next is 73° in 1949.

THE GROUND

What Perry stands on

Perry’s center stands about 1,390 ft above sea level. Within three miles the land runs from 1,170 ft to 1,740 ft, a difference of 570 ft: hilly country. The highest named summit within 15 miles is Kinter Hill, about 2,110 ft, 11 miles south-southeast.

Under the town center the state geologic map shows Allegheny Formation (sandstone), from the Carboniferous, 299 to 324 million years old.

The section below crosses 3 rock units mapped at the surface.
