AIR MAIL

Where today’s air came from

The air arriving over Millersburg about 5,000 feet above the ground was over the Canadian Prairies three days ago, about 1,710 miles back along its path. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the Pacific Northwest. It has stayed over land, which is why it feels dry. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.
