AIR MAIL

Where today’s air came from

The air arriving over Maxwell about 5,000 feet above the ground was over the northern Plains three days ago, and over the southern Plains a day ago, about 910 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 the Canadian Prairies; 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. 13, 2019

−5° on Nov. 13, 2019, the coldest reading for this week of the year since 1900. Next is 4° in 2005.

THE GROUND

What Maxwell stands on

Maxwell’s center stands about 900 ft above sea level. Within three miles the land runs from 850 ft to 1,020 ft, a difference of 170 ft: gently rolling country.

Under the town center the state geologic map shows Lower Cherokee Group and Raccoon Creek Group (shale, sandstone, siltstone), from the Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old.

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

Where Maxwell’s rain goes
