The +TNH response to WPAC MJO will probably warm the waters along the west coast over the next couple of weeks. Though the duration of that pattern is questionable given it has tended to be over-expressed in LR guidance all year.
I do agree that pattern will probably reverse during the second half of June as the MJO returns to the E-Hem amidst inception of south Asian monsoons, bringing about a discontinuous retrogression into -PNA/offshore high. Which would cool SSTAs once again.
But it could end up a wash in the end. Not sure there’s anything in the larger scale pattern to suggest substantial NPAC SSTA changes at all, actually.
The PDO is in a weird mode right now. The highest it went during the recent El Nino was -1.32 which is ridiculously low. The April reading was -2.09 and it has hit -3 a few times this decade.
