AIR MAIL

Where today’s air came from

The air arriving over Erath about 5,000 feet above the ground was over the Carolinas three days ago, and over the Florida peninsula a day ago, about 1,220 miles back along its path. It came down from about 15,900 feet up, warming and drying as it sank. Near the ground the air came from the Atlantic off the Carolinas; at 10,000 feet, from the Appalachians. It feels humid. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THIS WEEK IN 1993 Nov. 14–15, 1993

The wettest two days this week has seen

8.02 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 5.17 inches, fell in 2000.
