AIR MAIL

Where today’s air came from

The air arriving over Warren about 5,000 feet above the ground was over British Columbia three days ago, and over Ontario a day ago, about 2,460 miles back along its path. Near the ground the air came from British Columbia; at 10,000 feet, from the Gulf of Alaska. 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, 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 1893. Next is 74° in 1896.

THE GROUND

What Warren stands on

Warren’s center stands about 1,190 ft above sea level. Within three miles the land runs from 1,160 ft to 1,940 ft, a difference of 780 ft: hilly country. The highest named summit within 15 miles is Coal Knob, about 2,180 ft, 9 miles east.

Under the town center the state geologic map shows Chadakoin Formation (siltstone, shale), from the Late Devonian, 359 to 384 million years old.
