Where today’s air came from

The air arriving over Grattan about 5,000 feet above the ground was over the Pacific Northwest three days ago, and over the Great Lakes a day ago, about 1,890 miles back along its path. It came down from about 10,900 feet up, warming and drying as it sank. 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.
