The air arriving over Williamsfield about 5,000 feet above the ground was over British Columbia three days ago, and over the central Plains a day ago, about 2,370 miles back along its path. It came down from about 14,100 feet up, warming and drying as it sank. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
