AIR MAIL

Where today’s air came from

The air arriving over Chicora about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,320 miles back along its path. Near the ground the air came from British Columbia; at 10,000 feet, from the open Pacific. 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.
