AIR MAIL

Where today’s air came from

The air arriving over Holliston about 5,000 feet above the ground was over Canada three days ago, and over the Great Lakes a day ago, about 2,540 miles back along its path. 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.
