Yea, I am pretty sold on a weak la nina.
Here is an excerpt from my blog...not the end all be all, but climo tidbits like that add confidence:
Climatology is also strongly opposed to the notion of an el nino. Currently, the ONI for the AMJ tri-monthly period sits at -0.5c. Dating back to 1950, there are only four years that featured a negative ONI value for the AMJ tri-monthly period and went on to develop into a classified el nino.
They are:
1976: -0.3c
2018: -0.2c
1986:-0.1c
2006: -0.1c
Thus since 1950, no el nino event developed following an AMJ ONI value this low, which would make the development of an el nino later this year unprecedented. In fact, climatology actually favors the development of a la nina at this point. Only once since 1950 (1989 -0.6C) has there not been an official la nina registered during the autumn or winter following a AMJ tri-monthly ONI of -0.5c or lower.
