AIR MAIL

Where today’s air came from

The air arriving over Lockport about 5,000 feet above the ground was over Canada three days ago, and over the northern Plains a day ago, about 2,310 miles back along its path. It came down from about 12,200 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the open Pacific. 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, SIX YEARS AGO Nov. 11, 2020

The hottest this week has been

75° on Nov. 11, 2020, the hottest reading for this week of the year since 1895. Next is 75° in 2022.
