AIR MAIL

Where today’s air came from

The air arriving over Perry about 5,000 feet above the ground was over the Gulf of Alaska three days ago, and over the northern Plains a day ago, about 3,430 miles back along its path. It came down from about 15,500 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the Pacific north of Hawaii. 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.

The coldest this week has been

7° on Nov. 16, 1933, the coldest reading for this week of the year since 1872. Next is 10° in 1967.
