AIR MAIL

Where today’s air came from

The air arriving over Allegheny about 5,000 feet above the ground was over the Atlantic off the Carolinas three days ago, and over the Great Lakes a day ago, about 1,640 miles back along its path. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
