AIR MAIL

Where today’s air came from

The air arriving over Helmsburg about 5,000 feet above the ground was over British Columbia three days ago, and over the northern Plains a day ago, about 1,860 miles back along its path. Near the ground the air came from British Columbia; at 10,000 feet, from the Canadian Prairies. It has stayed over land, which is why it feels dry. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THIS WEEK, SEVEN YEARS AGO Nov. 13, 2019

The coldest this week has been

4° on Nov. 13, 2019, the coldest reading for this week of the year since 1922. Next is 5° in 1959.
