Without going into a competing long response, I  frankly just don't care about a warming planet. There's nothing I  can do about it aside from having a well insulated home (which I have since I receive the highest rating from my local energy provider for houses my size) and driving a fuel efficient vehicle. It is not, nor has it ever been, on my list of life's concerns at all. I care about weather imby and judge that weather from current conditions and progs. How those conditions got there, I don't care.

Oh, the "not me, it's you" defense. Lol

If you call trying to get to the bottom line of a post/position an attack, I  can't help you. But the bottom line is, you haven't denied my synopsis of your post/position because it's accurate. Which is fine. You can take whatever position you want. But clarity matters, that's all.

Many forecasts are for warmth but they are just going by enso. Many other factors to consider. 

Yeah, I will always point out that the coldest winter CONUS in the 21st century was during a strong la nina. Strong/super el ninos generally mean warmth, but not always.

It's too early to tell whether this upcoming winter is going to be warm, but if the models are still showing a cold signal in September, then people need to accept that it will probably be colder (and possibly snowier) winter.

Which super El Niños were cold winters (Dec-Mar)? 72-73: warm,  82-83: warm, 97-98: warm, 15-16: warm

*PHL-NYC-BOS corridor. Strong doesn’t count*

I assume you’re referring specifically to the NE US as the first 3 winters weren’t warm in the SE. They were pretty close to normal there.

He’s from Philly, so yes. I would love for him to let us know which super El Niño winters (Dec-Mar) since 1970 were cold in the PHL-NYC-BOS corridor. Strong doesn’t count. I’ll wait….   @PhiEaglesfan712

Yeah, there weren’t any cold winters in the East with super El Niños relative to the climatology at the time.

September is also early. Check back in November.

This will not be a cold winter ( definitely the first half )  we have to see how fast the EL nino weakens.

 Chris,

 The following is a better way to look at how 1997-8 did:

using the more appropriate/well centered climo base of 1981-2010 instead of 1961-90, which is earlier than 1997-8. Using the earlier, colder 1961-90 makes 1997-8 anomalies ~1F warmer than they actually were in many areas as you know vs the available best centered climo of 1981-2010: still mild in NE but not as mild and SE NN:

Yeah it will be warm. The question is more the magnitude of the warmth as that will make a big difference in terms of how much of the precip is wet vs white. There is a big difference between say +2 AN and +5-6 AN. 

[Terpeast]

I think it’s almost a given that the east coast winter will not be a cold one. For the MA, I’m thinking 2-4 AN vs 1991-2010 climo, warmer north and a bit cooler south.

STJ will be very active, launching one storm after another across the south. If we can time even marginal cold air with one of them, we could score big. Most of them will probably be rainstorms.

 I assume you’re referring to the NE US. Regarding the US as a whole, nothing is even close to a certainty, especially this far out. Even the NE is far from certain though cold there is admittedly quite unlikely. And the SE actually had a downright cold super-Nino winter: 1957-8.

The climatology period for the 1997-1998 super El Nino was 1961-1990. They don’t have 1941-1970 climatology maps on that site for 1972-1973. There also isn’t an 1951-1980 option for 1982-1983. So I used the closest time period that they offered at the site.
