AIR MAIL

Where today’s air came from

The air arriving over Millersburg about 5,000 feet above the ground was over British Columbia three days ago, about 2,390 miles back along its path. It came down from about 18,300 feet up, warming and drying as it sank. 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 and the GFS beyond them, nine paths at each of three heights.

THIS WEEK IN 2015 Nov. 17–18, 2015

The wettest two days this week has seen

3.42 inches of rain fell in two days, the most for this week of the year since records began in 1900. The next wettest, 2.98 inches, fell in 1928.
