AIR MAIL

Where today’s air came from

The air arriving over Wall about 5,000 feet above the ground was over the northern Rockies three days ago, about 830 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. It rose from near the ground on the way. Near the ground the air came from the northern Plains; at 10,000 feet, from the Pacific off the Northwest. 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.

Where Wall’s rain goes

A raindrop that lands in Wall reaches the Gulf of America by way of Cottonwood Creek, Lake Creek, Cottonwood Creek, the South Fork Bad, the Bad River, the Missouri and the Mississippi: about 2,450 river miles.
