AIR MAIL

Where today’s air came from

The air arriving over Jefferson about 5,000 feet above the ground was over the northern Plains three days ago, and over the Great Lakes a day ago, about 1,230 miles back along its path. Most of the nine paths traced from around the city agree. Near the ground the air came from Quebec; at 10,000 feet, from the California coast. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.
