AIR MAIL

Where today’s air came from

The air arriving over Punta Santiago about 5,000 feet above the ground was over the tropical Atlantic three days ago, about 940 miles back along its path. It came down from about 9,200 feet up, warming and drying as it sank. 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.

The wettest two days this week has seen
