  1. So it's going to be too low with heights in the southeast, but nail the northeast and mid atlantic? Good luck-
  2. It's affecting the pattern a great deal in the tropics, probably more so than any ENSO event in history at this time of year, but it's impact in the mid latitudes of the N HEM remains rather meager at this time.
  3. @stadiumwaveCan you link where you generated this image?
  4. That doesn't change the fact that it's initialization of the Pacific is off, so I would still adjust warmer....but that does make a little more sense. Yea, H5 for August at one month lead was good, but that doesn't mean that is always the case every month.
  5. Sure, but we have good reasons to believe that it isn't. I could still doubt that you're one of NYC's finest after you show me your badge and a pic of you sleeping in the cruiser, but that doesn't change the facts. No runs are key if the model incessantly suffers from an erroneous initialization. Again, this doesn't necessarily mean an awful winter is en route, it just means that CANSIPS output is highly flawed. Maybe we will make out okay and score a HECS...both can be true, and in fact, I suspect that they are.
  6. Yes, and I'm not being facetious....quite literally.
  7. -AO/+PNA winter en route.....confirms what I had already figured.
  8. Often times when seasonal guidance misses, it never caves....it just misses.
  9. Doesn't this fly in the face of your theory of summer +AO leading to winter time -AO?
  10. 83-84 and 16-17 early leaders in the clubhouse....
  11. The leak eastward of CANSIPS continued this month...that trend above was last month.
  12. Here is what I was getting at earlier RE CANSIPS...excerpt from my blog: Guidance is unanimous on notion that El Niño should begin to become more evenly distributed once again as the WWBs finally begin to weaken this fall, but they disagree on just how quickly and to what extent that will occur. The CANSIPS seems too aggressive in weakening the WWBs significantly by October, and the CFS evolution of shifting the event severely towards Modoki before an abrupt reversal to east-based is considered bizarre and thus disregarded. The JMA also seems far too aggressive in increasing the EMI to approximately .7 to .8, likely due to an early and exaggerated WWB retreat. Note that the June forecast already had the EMI crossing into the Modoki side of neutral for July and August, which has not happened. The CANSIPS has been making similar shifts eastward of the El Niño, as the trend from June to August for the peak OND period is clear. The European solution seems most reasonable, with a slow subsiding of the WWBs and accompanying neutralization of the EMI in late October, before a slight resurgence of WWBs and retreat eastward of the El Niño this winter. Here are the three distinct EMI scenarios. The ECMWF evolution of the El Niño EMI essentially neutralizing for winter is favored, which would ultimately render the El Niño as basin-wide.
  13. It was both.......the first half was bad luck, the second half sucked. Early season was decent owed to the low-scending solar, east QBO combo....but it turned ugly later.
  14. It was essentially neutral...very positive first half and negative 2nd half. The index calculations don't always match the composite, as was the case last year....it appeared to be a very deeply -WPO but it wasn't due to placement of the ridge.
  15. 97-98 turned out awfully, but it left a good bit on the table....it was actually dealt a pretty favorable hand from a polar perspective, which we don't have this year.
  16. 1983 is also the only super El Nino with a somewhat negative WPO.
