MJO is Now Quiet, Stratosphere Colder, Therefore, a Milder U.S. Pattern Ahead. But! There are Caveats!

Climate Impact Company U.S. Daily Report

Issued: Thursday December 11, 2025

Highlight: 3rd warmest autumn on record in the U.S.; November 4th warmest.

Fig. 1-2: NOV-25 state temperature and precipitation rankings.

Fig. 3-4: Meteorological autumn (SEP/OCT/NOV 2025) state temperature and precipitation rankings.

Discussion: November and meteorological autumn (2025) were exceptionally warm, ranking 4th and 3rd warmest respectively. Oregon and the Interior West plus Texas observed record warmth during the period. The Great Plains observed a MUCH WARMER than normal autumn season although the Midwest cooled to slightly above normal in November. The East was marginally warm during autumn cooling to near normal across the Northeast in November. Autumn (and November) was also somewhat drier than normal ranking in the top 20% dry years (1895-2025). The driest region is the Southeast U.S., particularly during November and including Florida which is a surprise as no tropical cyclone influence affected the state during autumn. The Midwest observed a dry autumn although not quite as dry in November. Arizona observed MUCH ABOVE normal rainfall during the autumn season.
