AIR MAIL

Where today’s air came from

The air arriving over Bath about 5,000 feet above the ground was over the northern Rockies three days ago, and over the central Plains a day ago, about 860 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. It rose from near the ground on the way. 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.

THE GROUND

What Bath stands on

Bath’s center stands about 1,300 ft above sea level. Within three miles the land runs from 1,270 ft to 1,310 ft, a difference of 40 ft: nearly flat ground.

Under the town center the state geologic map shows Pierre Shale (shale, bentonite), from the Late Cretaceous, 66 to 100 million years old.
