AIR MAIL

Where today’s air came from

The air arriving over Orchard Hills about 5,000 feet above the ground was over Canada three days ago, and over the northern Plains a day ago, about 2,750 miles back along its path. It came down from about 16,200 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; 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

77° on Nov. 11, 2020, the hottest reading for this week of the year since 1953. Next is 74° in 1993.
