AIR MAIL

Where today’s air came from

The air arriving over Filer about 5,000 feet above the ground was over the Pacific Northwest three days ago, about 510 miles back along its path. Most of the nine paths traced from around the city agree. It came down from about 16,000 feet up, warming and drying as it sank. Near the ground the air came from the Pacific Northwest; at 10,000 feet, from the Great Basin. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.
