Sorry. Bad wording on my part. The southeast PA reference was regarding where the complex heads as it moves out of western PA.- 2,404 replies

E PA/NJ/DE Autumn 2026 Obs/Discussion
Newman replied to PhiEaglesfan712's topic in Philadelphia Region
I've honestly not taken much of a long look into the upcoming 2026-27 winter prospects but did take a quick peek at it just now. First of all, as of right now, it seems like the tropical Pacific and North Pacific *appear* to be out of sync and not quite coupled. Obviously we have a super Nino ongoing and expected to peak this fall. We're coming off a very negative SOI in July, I think the lowest since the 1980s. When taking a seasonal correlation of DJF 500mb heights to ASO SOI, you get a pretty canonical look. Positive correlations between SOI and 500mb heights in the SE US, meaning the negative SOI usually correlates to negative heights across the southern US, and then positive heights across the northern tier. However, we may have a competing signal given there is (currently) a lag in response of the PDO to the developing Nino. August PDO is still negative, which is counterintuitive to what you'd expect during a strong Nino. In fact, I simply can't find any year at all that followed a typical ENSO progression to this year (strong to super Nino developing, peaking in the fall, then waning and eventually switching to Nina the following year) and also had a negative PDO. We still have time before winter for the North Pacific to respond, but for posterity, here is the correlation map between ASO PDO and DJF 500mb heights. It's actually a very impressive negative correlation in the SE US, one that is more statistically significant than the SOI signal. The negative PDO usually correlates to positive heights in the SE US (big ridge in the eastern US), and that is opposite to the map above. So that begs the question here... IF the PDO continues to lag into the winter and we have a Nina like North Pacific but Nino tropical Pacific, how will the winter turn out? I'm under the opinion that we will see a North Pacific "coupling" this fall with the tropics, but I'm cautious about it until I see it. We've seen this persistent negative PDO for so long, aided by the marine heat wave off Japan, so idk. Just for further posterity, here is the 500mb height anomalies of 4 super Nino winters we've seen recently, which looks like a pretty canonical Nino pattern in the mean. But with Nina effects lingering, will we see a similar pattern this year? Long winded thoughts, but my idea this winter is a pretty torchy start into December and early January. We might see some brief negative NAO spikes by late Jan and Feb which is when we'll need to time an active STJ storm with an arctic front that's pressed off the coast. Even if not, probably some chances for cold spells. I'm also not a long range forecaster so take everything with a grain of salt LOL @GaWx What are you thinking/seeing for this winter in the East? -

2026-2027 Record-breaking El Nino
PhiEaglesfan712 replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
Do we now have a relative and a traditional PDO now (like we do with the ONI)? This one shows July as -2.14 and August as -1.84: https://www.ncei.noaa.gov/pub/data/cmb/ersst/v5/index/ersst.v5.pdo.dat -

That says August. The August forecast isn’t new. The Sept 1st forecast is the new one we’re waiting for. The monthly Euro forecasts are normally released on the 5th of the month.
