AIR MAIL

Where today’s air came from

The air arriving over Leet about 5,000 feet above the ground was over British Columbia three days ago, and over Ontario a day ago, about 2,500 miles back along its path. It came down from about 11,100 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; 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 IN 1933 Nov. 16, 1933

The coldest this week has been

9° on Nov. 16, 1933, the coldest reading for this week of the year since 1871. Next is 10° in 1986.

What Leet stands on

Leet’s center stands about 1,150 ft above sea level. Within three miles the land runs from 680 ft to 1,210 ft, a difference of 530 ft: hilly country. The highest named summit within 15 miles is Big Knob, about 1,400 ft, 10 miles north.

Under the town center the state geologic map shows Casselman Formation (shale, clastic), from the Carboniferous, 299 to 324 million years old.
