AIR MAIL

Where today’s air came from

The air arriving over Clinton about 5,000 feet above the ground was over the Gulf of Alaska three days ago, and over Ontario a day ago, about 2,560 miles back along its path. It came down from about 12,400 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from a point about 3,560 miles to the west. 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 1933 Nov. 16, 1933

The coldest this week has been

9° on Nov. 16, 1933, the coldest reading for this week of the year since 1871. Next is 10° in 1986.

THE GROUND

What Clinton stands on

Clinton’s center stands about 1,230 ft above sea level. Within three miles the land runs from 930 ft to 1,260 ft, a difference of 330 ft: rolling country. The highest named summit within 15 miles is Quakers Knob, about 1,430 ft, 12 miles south-southwest.

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