QBO is not unfavorable this year and La Niña is still going to be weak. This seems like splitting hairs to me...and believe me, I want a repeat of last winter like a hole in the head.

although I didn't like the results, I would run the 500mb pattern back in a heartbeat. that winter was a clinic on how to get the least amount of snow with favorable 500mb patterns

I’m not saying the QBO is unfavorable at all. As to solar, yes, I’d agree that solar is similar. Both sunspot and solar flux numbers are back up over 200. And it looks like we are about to have a big uptick in geomag activity

Last year is not a perfect analog, but it is variable IMO...it's one of my primary analogs.

I would prefer to run it back with a more neutral WPO.

I'm not so sure I'd be looking at solar at this point. True, there's been a big jump in activity the last day or 2, but that's after a big drop. The overall trend is down looking at everything at the link below. Plus, it's too early. If we're rolling ahead hot and heavy come November, imho, then we take a 2nd look at possible curveballs to the forecast.

We had a warm, humid summer here, and while once again, extreme temps were not a thing (14 days of 90F+, which is only 1 day more than normal, and only 4 of these days were 93+) it was the warm humid nights that made their mark. 

Yet now, we are in a stretch of a what will be about 10 days straight of unseasonably cool nights, several of them flirting in record low territory, so to say that summers back is broken is an understatement. The trees are starting to get some color as well. 

Through yesterday, we are now at .4 above average for the month around here. Tomorrow will be well below average and the lows around here for sure will be below average the rest of the month. The highs might be too but Sunday might be close. I think we’re going to end the month slightly below average with the low temperatures leading the way which has become quite unusual in recent times.

I agree. The Niña is tipping its hand much earlier this year than last, there’s a -IOD event now and the NW Pacific is even warmer. There’s also a very pronounced -PMM and we have a deep -AAM, whereas last year was very +AAM/Nino like. Last year by this time we had a parade of recurving tropical and extratropical storms training over the inferno SSTS off Japan cooling/upwelling them, not happening this time around. In fact the -PDO is even stronger now with SSTS of 11 degrees F above normal in that area….that’s staggering. And obvious big changes in the Atlantic with the big persistent cold pool south of Greenland and up Davis Straight

EDIT: We’ve also had a QBO flip from + to -
 
 

The subsurface accumulation of warmth is really off the charts. During the winter there was a trough east of Japan. But the SSTs weren’t able to cool much with so much heat below the surface.
