AIR MAIL

Where today’s air came from

The air arriving over Streator about 5,000 feet above the ground was over British Columbia three days ago, and over the central Plains a day ago, about 1,860 miles back along its path. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from British Columbia. 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, FOUR YEARS AGO Nov. 11, 2022

The hottest this week has been

75° on Nov. 11, 2022, the hottest reading for this week of the year since 1941. Next is 74° in 2020.

THE GROUND

What Streator stands on

Streator’s center stands about 630 ft above sea level. Within three miles the land runs from 560 ft to 660 ft, a difference of 100 ft: gently rolling country.

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.
