AIR MAIL

Where today’s air came from

The air arriving over St. Thomas 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 1,580 miles back along its path. Near the ground the air came from the western Atlantic; at 10,000 feet, from the Atlantic off Florida. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
