AIR MAIL

Where today’s air came from

The air arriving over Du Bois about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the Great Lakes a day ago, about 1,650 miles back along its path. Near the ground the air came from the northern Plains; at 10,000 feet, from the northern Rockies. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.
