AIR MAIL

Where today’s air came from

The air arriving over Clayton about 5,000 feet above the ground was over British Columbia three days ago, and over the northern Plains a day ago, about 2,630 miles back along its path. It came down from about 14,800 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the Pacific Northwest. It has stayed over land, which is why it feels dry. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THIS WEEK, SEVEN YEARS AGO Nov. 13, 2019

The coldest this week has been

5° on Nov. 13, 2019, the coldest reading for this week of the year since 1893. Next is 9° in 1959.
