AIR MAIL

Where today’s air came from

The air arriving over Wiscasset about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the Great Lakes a day ago, about 2,120 miles back along its path. Near the ground the air came from the northern Plains; at 10,000 feet, from Canada. 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, FOUR YEARS AGO Nov. 12, 2022

The hottest this week has been

72° on Nov. 12, 2022, the hottest reading for this week of the year since 1996. Next is 67° in 2020.

THE GROUND

What Wiscasset stands on

Wiscasset’s center stands about 50 ft above sea level. Within three miles the land runs from 0 ft to 260 ft, a difference of 260 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Beech Hill, about 560 ft, 14 miles north.

Under the town center the state geologic map shows Ordovician - Precambrian Z Cape Elizabeth Formation (slate), from the Neoproterozoic to Ordovician, 445 to 1,000 million years old.
