AIR MAIL

Where today’s air came from

The air arriving over Byron about 5,000 feet above the ground was over the Gulf of Alaska three days ago, and over Ontario a day ago, about 2,620 miles back along its path. Near the ground the air came from Canada; 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, SIX YEARS AGO Nov. 11, 2020

The hottest this week has been

75° on Nov. 11, 2020, the hottest reading for this week of the year since 1911. Next is 73° in 2012.

THE GROUND

What Byron stands on

Byron’s center stands about 610 ft above sea level. Within three miles the land runs from 590 ft to 740 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Scarff Hill, about 1,420 ft, 14 miles south.

Under the town center the state geologic map shows Camillus, Syracuse, and Vernon Formations (shale), from the Silurian, 422 to 428 million years old.

The section below crosses 11 rock units mapped at the surface.
