AIR MAIL

Where today’s air came from

The air arriving over Medford about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,890 miles back along its path. It came down from about 13,400 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.
