AIR MAIL

Where today’s air came from

The air arriving over St. Leo about 5,000 feet above the ground was over the Caribbean three days ago, and over the eastern Gulf of America a day ago, about 610 miles back along its path. Near the ground the air came from the Carolinas; at 10,000 feet, from a point about 500 miles to the southwest. Air off the water carries moisture, which is why it feels humid. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

90° on Nov. 13, 2008, the hottest reading for this week of the year since 1895. Next is 90° in 2023.

What St. Leo stands on

St. Leo’s center stands about 170 ft above sea level. Within three miles the land runs from 80 ft to 230 ft, a difference of 150 ft: gently rolling country.

Under the town center the state geologic map shows Hawthorn Group, Undifferentiated (sand, clay), from the Miocene, 5.3 to 23 million years old.

The section below crosses 2 rock units mapped at the surface.
