AIR MAIL

Where today’s air came from

The air arriving over East Brooklyn about 5,000 feet above the ground was over the open Pacific three days ago, and over the northern Plains a day ago, about 2,770 miles back along its path. It came down from about 12,100 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from British Columbia. 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.

THIS WEEK, FOUR YEARS AGO Nov. 11, 2022

The hottest this week has been

75° on Nov. 11, 2022, the hottest reading for this week of the year since 1990. Next is 74° in 1999.
