In the post last night I wrote:The SSTA warm pool is now located between 120 and 150W and 30-60N in the Northeast pacific – that favors a –EPO and weakening pacific jet. Recall in the winter outlook I said that the SSTA warm pool would eventually re-develop in that region and force the changes in the upper level pattern which would allow the PAC jet to slow and the PNA to turn predominantly positive. The ideas were correct; however I forecasted the onset of it two weeks too early.
So it will LIKELY be transient, and Im not concerned about it at all.
