AIR MAIL

Where today’s air came from

The air arriving over Jonesboro about 5,000 feet above the ground was over Canada three days ago, and over Ontario a day ago, about 2,710 miles back along its path. It came down from about 10,900 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from Canada. 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.

THE GROUND

What Jonesboro stands on

Jonesboro’s center stands about 40 ft above sea level. Within three miles the land runs from 0 ft to 220 ft, a difference of 220 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Peaked Mountain, about 540 ft, 9 miles northwest.

Under the town center the state geologic map shows Devonian granite, from the Devonian, 359 to 422 million years old.

The section below crosses 7 rock units mapped at the surface.
