AIR MAIL

Where today’s air came from

The air arriving over Hewlett Bay Park about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the Great Lakes a day ago, about 2,140 miles back along its path. Most of the nine paths traced from around the city agree. Near the ground the air came from the Ohio Valley; at 10,000 feet, from British Columbia. 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.
