AIR MAIL

Where today’s air came from

The air arriving over Platte about 5,000 feet above the ground was over the southern Rockies three days ago, and over the southern Plains a day ago, about 850 miles back along its path. Most of the nine paths traced from around the city agree. Near the ground the air came from the northern Rockies; at 10,000 feet, from the northern Plains. It has stayed over land, which is why it feels dry. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THIS WEEK, ONE YEAR AGO Nov. 15, 2025

The hottest this week has been

83° on Nov. 15, 2025, the hottest reading for this week of the year since 1898. Next is 81° in 1953.

THE GROUND

What Platte stands on

Platte’s center stands about 1,600 ft above sea level. Within three miles the land runs from 1,460 ft to 1,670 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Took Tay Hill, about 1,940 ft, 6 miles south.

Under the town center the state geologic map shows Pierre Shale (shale, bentonite), from the Late Cretaceous, 66 to 100 million years old.

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