AIR MAIL

Where today’s air came from

The air arriving over Nashville about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the Great Lakes a day ago, about 1,720 miles back along its path. Most of the nine paths traced from around the city agree. Near the ground the air came from Texas; at 10,000 feet, from the central Plains. 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

8° on Nov. 12, 2019, the coldest reading for this week of the year since 1962. Next is 9° in 1986.

THE GROUND

What Nashville stands on

Nashville’s center stands about 520 ft above sea level. Within three miles the land runs from 450 ft to 550 ft, a difference of 100 ft: gently rolling country.

Under the town center the state geologic map shows Bond Formation (shale, sandstone, limestone), from the Late Pennsylvanian, 304 to 307 million years old.

The section below crosses 2 rock units mapped at the surface.
