AIR MAIL

Where today’s air came from

The air arriving over Colchester about 5,000 feet above the ground was over the Atlantic off the Carolinas three days ago, and over New England a day ago, about 1,410 miles back along its path. Near the ground the air came from Canada; at 10,000 feet, from the Mid-Atlantic. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
