The Weather West blog has a long discussion of the evolving El Niño weather pattern, concluding:
It’s worth noting that seasonal forecasts have strongly hinted at precisely this evolution [Enhanced Asian Jetstream] for many months now–showing a dry autumn, and equivocal December, and subsequently a very wet January-March period for all of California. Right now, model solutions for the first 2 weeks in January are converging on just such an outcome. So, for now, I’d advise everyone to enjoy the cold storm this week and keep a close eye on what appears to be very promising evidence that our long-advertised pattern shift will finally arrive in early January.
Stay Tuned, 2016 is going to be an interesting weather year.
