The above average SSTs off the West Coast have been much reduced over the last couple of months.  "The Blob," in my opinion, was never really well defined (which exact region?) so it is dificult for me to comment on it.   An enhanced, zonally elongated Pacific jet stream is helping to cool down SSTs, but I agree that it is shifted farther north than is typical during El Nino.  So instead of southern CA obtaining more precipitation, it is the Pacific Northwest that has been targeted.  There are probably multiple factors driving this shift--- I'm inclined to think the more positive Arctic Oscillation (AO) has been a prime factor in this shift.

However, we are now seeing changes in the circulation over the Pacific, so we expect more classical El Nino-like impacts to become more prominent.
