AIR MAIL

Where today’s air came from

The air arriving over South Sumter about 5,000 feet above the ground was over the Mississippi Valley three days ago, and over the Appalachians a day ago, about 680 miles back along its path. Most of the nine paths traced from around the city agree. Near the ground the air came from the Mid-Atlantic; at 10,000 feet, from the northern Rockies. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THIS WEEK IN 2008 Nov. 14–15, 2008

The wettest two days this week has seen

3.33 inches of rain fell in two days, the most for this week of the year since records began in 1901. The next wettest, 2.85 inches, fell in 1979.
