AIR MAIL

Where today’s air came from

The air arriving over Sumpter about 5,000 feet above the ground was over the central Plains three days ago, and over the Great Lakes a day ago, about 1,110 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. 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.
