September 2026 was the warmest one on record for the Contiguous U.S. according to PRISM climate data. If confirmed by NOAA it would be the first time there will be three back-to-back record months JUL, AUG, SEP — a concerning first thanks to climate change. (via @climateguyw.bsky.social)

No surprises for anyone living in SoCal, but the last couple of days have been very hot for Oct in most areas, with widespread 100F+ today even pretty close to coast. Quite a few daily records, and maybe a monthly record or two, broken--with scattered records elsewhere in West.
Map from coolwx.org showing current record-breaking temperatures across the CONUS. There are numerous locations near or at record levels across SoCal, mostly daily vs monthly, with scattered locations widely distributed across the West.

Someone asked me how water vapor would respond to El Nino and record temps early next year? Clearly it seemed the globe should be in record territory. And according to the Euro ensembles we are - about 3-4% above record water vapor in Dec, Jan, Feb!…
