AIR MAIL

Where today’s air came from

The air arriving over Westhampton about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,670 miles back along its path. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from British Columbia. 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

72° on Nov. 11, 2020, the hottest reading for this week of the year since 1926. Next is 71° in 2022.

THE GROUND

What Westhampton stands on

Westhampton’s center stands about 640 ft above sea level. Within three miles the land runs from 330 ft to 1,500 ft, a difference of 1,170 ft: steep hill country. The highest named summit within 15 miles is Garnet Hill, about 2,190 ft, 15 miles west-northwest.

Under the town center the state geologic map shows Gile Mountain Formation (phyllite, schist), from the Early Devonian, 394 to 422 million years old.

The section below crosses 11 rock units mapped at the surface.
