AIR MAIL

Where today’s air came from

The air arriving over South Greeley about 5,000 feet above the ground was over the Great Basin three days ago, and over the northern Rockies a day ago, about 820 miles back along its path. It came down from about 12,500 feet up, warming and drying as it sank. 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.

75° on Nov. 15, 1999, the hottest reading for this week of the year since 1871. Next is 75° in 2016.
