AIR MAIL

Where today’s air came from

The air arriving over Clinton about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,490 miles back along its path. It came down from about 10,100 feet up, warming and drying as it sank. 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, FOUR YEARS AGO Nov. 12, 2022

The hottest this week has been

75° on Nov. 12, 2022, the hottest reading for this week of the year since 1948. Next is 70° in 2024.

What Clinton stands on

Clinton’s center stands about 30 ft above sea level. Within three miles the land runs from 0 ft to 240 ft, a difference of 240 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Totoket Mountain, about 760 ft, 14 miles northwest.

Under the town center the state geologic map shows Potter Hill Granite Gneiss plus Narragansett Pier Granite (granite, gneiss), from the Neoproterozoic to Permian, 252 to 1,000 million years old.
