AIR MAIL

Where today’s air came from

The air arriving over Carolina about 5,000 feet above the ground was over the tropical Atlantic three days ago, about 1,040 miles back along its path. Air off the water carries moisture, which is why it feels humid. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
