AIR MAIL

Where today’s air came from

The air arriving over Washington about 5,000 feet above the ground was over Canada three days ago, and over the northern Plains a day ago, about 2,770 miles back along its path. It came down from about 17,800 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the open Pacific. 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.

THIS WEEK, SIX YEARS AGO Nov. 11, 2020

The hottest this week has been

77° on Nov. 11, 2020, the hottest reading for this week of the year since 1953. Next is 74° in 1993.

THE GROUND

What Washington stands on

Washington’s center stands about 1,290 ft above sea level. Within three miles the land runs from 1,000 ft to 1,380 ft, a difference of 380 ft: rolling country.

Under the town center the state geologic map shows Glenshaw Formation (shale), from the Carboniferous, 299 to 324 million years old.

The section below crosses 3 rock units mapped at the surface.

THE WATER

Where Washington’s rain goes

A raindrop that lands in Washington reaches the Gulf of America by way of Beaver Run, the Kiskiminetas, the Allegheny, the Ohio and the Mississippi: about 2,000 river miles.
