AIR MAIL

Where today’s air came from

The air arriving over West Nottingham about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,750 miles back along its path. It came down from about 15,000 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; 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, TWO YEARS AGO Nov. 11, 2024

The hottest this week has been

74° on Nov. 11, 2024, the hottest reading for this week of the year since 1978. Next is 72° in 1993.

What West Nottingham stands on

West Nottingham’s center stands about 390 ft above sea level. Within three miles the land runs from 230 ft to 550 ft, a difference of 320 ft: rolling country.

Under the town center the state geologic map shows Ultramafic rocks (serpentinite), from the Paleozoic, 252 to 542 million years old.

The section below crosses 9 rock units mapped at the surface.
