AIR MAIL

Where today’s air came from

The air arriving over Homer about 5,000 feet above the ground was over British Columbia three days ago, and over the central Plains a day ago, about 2,470 miles back along its path. It came down from about 13,700 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the northern Plains. 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, SEVEN YEARS AGO Nov. 12, 2019

The coldest this week has been

0° on Nov. 12, 2019, the coldest reading for this week of the year since 1888. Next is 3° in 1959.

THE GROUND

What Homer stands on

Homer’s center stands about 680 ft above sea level. Within three miles the land runs from 640 ft to 690 ft, a difference of 50 ft: nearly flat ground.

Under the town center the state geologic map shows Shelburn-Patoka Formations undivided (shale, limestone), from the Late Pennsylvanian, 304 to 307 million years old.

The section below crosses 3 rock units mapped at the surface.

THE WATER

Where Homer’s rain goes

A raindrop that lands in Homer reaches the Gulf of America by way of the Salt Fork, the Vermilion, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,400 river miles.
