AIR MAIL

Where today’s air came from

The air arriving over Sandoval about 5,000 feet above the ground was over a point about 1,200 miles to the east three days ago, and over the Gulf Coast a day ago, about 1,260 miles back along its path. Near the ground the air came from Georgia; at 10,000 feet, from Alabama and Mississippi. Air off the water carries moisture, which is why it feels humid. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THIS WEEK IN 1995 Nov. 16–17, 1995

The wettest two days this week has seen

3.25 inches of rain fell in two days, the most for this week of the year since records began in 1962. The next wettest, 2.85 inches, fell in 2003.
