AIR MAIL

Where today’s air came from

The air arriving over Buffalo about 5,000 feet above the ground was over the open Pacific three days ago, and over the central Plains a day ago, about 3,020 miles back along its path. It came down from about 13,900 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from British Columbia. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THIS WEEK, TEN YEARS AGO Nov. 17, 2016

The hottest this week has been

79° on Nov. 17, 2016, the hottest reading for this week of the year since 1879. Next is 78° in 1955.

THE GROUND

What Buffalo stands on

Buffalo’s center stands about 610 ft above sea level. Within three miles the land runs from 560 ft to 640 ft, a difference of 80 ft: gently rolling country. The highest named summit within 15 miles is Elkhart Hill, about 820 ft, 12 miles north-northwest.

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 2 rock units mapped at the surface.
