AIR MAIL

Where today’s air came from

The air arriving over Ulysses about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the Great Lakes a day ago, about 2,180 miles back along its path. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the Gulf of Alaska. 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

74° on Nov. 11, 2020, the hottest reading for this week of the year since 1956. Next is 69° in 2012.

THE GROUND

What Ulysses stands on

Ulysses’s center stands about 2,230 ft above sea level. Within three miles the land runs from 1,940 ft to 2,540 ft, a difference of 600 ft: hilly country. The highest named summit within 15 miles is Bailey Hill, about 2,590 ft, 3 miles southeast.

THE WATER

Where Ulysses’s rain goes

A raindrop that lands in Ulysses reaches Lake Ontario by way of the Genesee: about 160 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
