AIR MAIL

Where today’s air came from

The air arriving over Mansfield about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the central Plains a day ago, about 1,230 miles back along its path. Near the ground the air came from British Columbia; at 10,000 feet, from the Pacific north of Hawaii. 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 IN 2014 Nov. 14, 2014

The coldest this week has been

−17° on Nov. 14, 2014, the coldest reading for this week of the year since 1893. Next is −15° in 1959.
