AIR MAIL

Where today’s air came from

The air arriving over Windsor about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,730 miles back along its path. Near the ground the air came from British Columbia; 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, NINE YEARS AGO Nov. 12, 2017

The coldest this week has been

20° on Nov. 12, 2017, the coldest reading for this week of the year since 1948. Next is 21° in 2023.

THE GROUND

What Windsor stands on

Windsor’s center stands about 680 ft above sea level. Within three miles the land runs from 570 ft to 960 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Huntrick Hill, about 1,070 ft, 13 miles southwest.

Under the town center the state geologic map shows Marburg Schist (phyllite, mica-schist), from the Paleozoic, 252 to 542 million years old.

The section below crosses 8 rock units mapped at the surface.
