AIR MAIL

Where today’s air came from

The air arriving over Shiloh about 5,000 feet above the ground was over the open Pacific three days ago, about 3,030 miles back along its path. It came down from about 14,900 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the northern Plains. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
