AIR MAIL

Where today’s air came from

The air arriving over West Norriton 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 Quebec; at 10,000 feet, from the Atlantic off the Carolinas. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
