AIR MAIL

Where today’s air came from

The air arriving over Rossiter about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,220 miles back along its path. Near the ground the air came from British Columbia; at 10,000 feet, from the Gulf of Alaska. 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

76° on Nov. 11, 2020, the hottest reading for this week of the year since 1943. Next is 73° in 1949.
