AIR MAIL

Where today’s air came from

The air arriving over West Brooklyn about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the central Plains a day ago, about 1,210 miles back along its path. It rose from near the ground on the way. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the northern Rockies. 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. 12, 2019

The coldest this week has been

1° on Nov. 12, 2019, the coldest reading for this week of the year since 1912. Next is 3° in 1986.
