AIR MAIL

Where today’s air came from

The air arriving over Warrensburg about 5,000 feet above the ground was over the open Pacific three days ago, and over the central Plains a day ago, about 2,900 miles back along its path. It came down from about 14,500 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the Pacific Northwest. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THIS WEEK IN 2009 Nov. 16–17, 2009

The wettest two days this week has seen

3.66 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 3.04 inches, fell in 1964.
