AIR MAIL

Where today’s air came from

The air arriving over Crescent about 5,000 feet above the ground was over Texas three days ago, and over the southern Plains a day ago, about 850 miles back along its path. Near the ground the air came from the Canadian Prairies; 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.
