    It’s not about setting anyone straight. Not sure why I keep getting quoted multiple times when I am not in that thread. But I have looked at the responses and statements and have some replies. First, we have never had 9 consecutive winters this warm in the Northeast before. One of the dominant themes is that the rapid expansion of the WPAC warm pool has lead to more forcing from MJO 4-7 which had been written up in numerous studies. Forcing in this region is warm for the Northeast. So it makes perfect sense that it has been this warm in our region over the last 9 winters.  I never said that we couldn’t eventually see another colder than average winter in the Northeast. Just that as long as this WPAC warm pool remains so prominent, it will probably load the dice for more warmer than colder winters over time. I am not sure what could shift this but would be open to a change if some new region of tropical forcing can emerge.

    The reduction in the snowfall has occurred a little later beginning with the 18-19 season. It has resulted in 5 out of the last 6 winters with below normal snowfall in NYC. It seems to be a combo of warmer than normal winters and the more hostile Pacific patterns. The epic 2010-2018 snowfall period carried over into the beginning of the warm winter period that started in December 15 with the historic +13.3 departure. My guess is that the 2010s will stand as our snowiest recent decade. When the 2020s are complete , we are on track for a significantly lower snowfall period vs the 2010s even if snowfall can improve next several seasons. But this doesn’t mean that we can’t have some great snowfall seasons in the mix like 20-21 along the way. Snowfall has been more variable while winters have been steadily warming over the years.

    Second, the warm blob in the NEPAC from 13-14 to 14-15 was the result of tropical forcing and not the direct cause of the pattern. This pattern quickly shifted after 2 years during the winters but became prominent in the warm season. It was a direct result of the tropical driven Rossby wave pattern. The record PAC NW heatwave a few summers ago and numerous Western drought seasons with the powerful Western Ridge were part of this pattern. An interesting question for study is why the seasonal shift occurred after the 13-14 and 14-15 winters?

    MJO is the latest fad to explain a small sample size of outcomes IMHO. We’ve seen it for decades now. 
     

    - Late 1990s literature blamed the big reversal of NAO/AO to predominately positive phases on CC

    -early 2010s literature blamed the big flip back to -AO/NAO on CC via melting sea ice

    - mid-2010s literature blamed the western drought and cold eastern winters in the pacific warm blob due to CC

     

    I remember being called a climate denier for being skeptical of the sea ice theory circa 2012 or so. It’s hard to have rational discussions about these attribution studies with people who don’t really care about rigor. 
     

    MJO is popular right now because “it makes sense” in explaining a small sample of shit winters in the east. To your point, maybe the MJO stuff is true in a vacuum but people are over-attributing the MJO to our own weather. 
     

    What is going to be the next explanation when we get a couple of cold-loses winters in a row?

    I agree. Enjoy whatever we get for Saturday, which my guess is probably a plowable event (maybe something like 3-5 inches?). The final few days of this month and early March looks ugly

    It feels odd to read posts from you that are pro snow haha. Either way, I hope you’re correct about the 3-5

    What a winter for Anchorage. One of their coldest/snowiest on record then they roll in with a daily record high yesterday. They must be jumping for joy...unless they like the cold. 

    It’s the only place currently that can sustain winter weather with the unfavorable MJO phases.

    @forkyfork and @bluewave are correct, the unfavorable mjo phases are here to stay. Winters will be more like the past few years then the snowy early 2000’s

    Unfortunately icon is usually too far north so I wouldn't use it. I like seeing the rgem so robust

    I thought the icon did well with yesterday’s event. It never bought into a nyc jackpot
