AIR MAIL

Where today’s air came from

The air arriving over Mahoning about 5,000 feet above the ground was over the western Atlantic three days ago, and over the Great Lakes a day ago, about 1,300 miles back along its path. Near the ground the air came from the western Atlantic; at 10,000 feet, from Quebec. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
