AIR MAIL

Where today’s air came from

The air arriving over North Haven about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,560 miles back along its path. Near the ground the air came from the Ohio Valley; 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, SIX YEARS AGO Nov. 11, 2020

The hottest this week has been

74° on Nov. 11, 2020, the hottest reading for this week of the year since 1930. Next is 72° in 1993.
