    It's early. I generally like how things look in the ENSO region right now- neutral but the SST distribution has the anomalous warmth focused more in the western Pacific. If that holds we could end up with the atmosphere behaving more Nino-ish than last winter, assuming the MJO or some other forcing mechanism doesn't overwhelm again. Looking at the SSTs in the PDO region, it looks like it may be heading in the direction we want(da blob!), but its difficult to tell at this juncture and we have seen this somewhat nebulous look before, only to have the anomalies dissipate/shift moving deeper into Fall. Again it's early. Also have to like the QBO trend as we head towards winter this year.

    You'd always see this ENSO configuration in a generally warm Earth because of land/mountain torque.. Any warmer and it's biased El Nino (Nino 1.2 and 3 are cold). 

  2. Looking at medium/long range models, it's really hard for a +PNA to form. Skewed toward -PDO, like we've seen 2014-2019 in the long wavelength season. The Aleutian High becomes a block in about September and the same is holding true this year.

    I mention this because we had +PNA all year up until about 7-10 days ago. This -PDO is a pattern that will hold.
