AIR MAIL

Where today’s air came from

The air arriving over Kahaluu about 5,000 feet above the ground was over the Pacific south of Hawaii three days ago, about 1,000 miles back along its path. It rose from near the ground on the way. Air off the water carries moisture, which is why it feels humid. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

The coldest this week has been

57° on Nov. 14, 2017, the coldest reading for this week of the year since 1942. Next is 63° in 1946.
