Fall 2025 Medium/Long Range Discussion
CheeselandSkies replied to Chicago Storm's topic in Lakes/Ohio Valley
Long as that doesn't mean winter hangs around till the end of April the following year like it did then. -
November 2025 general discussions and probable topic derailings ...
ORH_wxman replied to Typhoon Tip's topic in New England
Not sure we’d need any NAO ridging with that look. That’s pretty cold. That SE Canada and Atlantic look is very reminiscent of early to mid December 2007…the WPO is more negative than ‘07 though…that’s pure cross polar there -
Sure, anyone who points this out is a denier...it's the same dogma that leads to "everything about climate change is CATASTROPHIC and EVIL!"

What could go wrong?

Good to hear. Every NAO that we’ve had over the last 3-4 years hasn’t done Jack for us. In fact it’s hurt us more than anything. I’ll take some random transient ridging and run, thank you very much. -
Yep. Maybe the Mountains will get a few Flakes from that.

Utter nonsense

2025-2026 ENSO

Below is an illustration of an extreme forecast that is being pushed on Twitter/X despite the lack of evidence to actually support the idea (e.g., small pool of deep cold in the Northern Hemisphere) and the lack of skill in guidance from this far out: "Lower Rio Grande Valley" doesn't specify a specific point or location for purposes of verification, so it will be excluded. Here's the forecast coupled with December 2000-2024 statistics: This illustrative example will be verified at the end of December. Given the estimated probabilities for various outcomes, the odds are strongly against the extreme forecast verifying in more than one of the above locations. -
Mid to long range discussion- 2025

At least Black Friday is trending colder and colder -
I don’t dislike the Euro for next weekend at all. .
-
Yeah it's 75-80 east of the Blue Ridge today even. SER is strong the next few weeks. Hopefully it decides to go on vacation until March

Central PA Fall Discussions and Obs
Itstrainingtime replied to ChescoWx's topic in Upstate New York/Pennsylvania
Exactly the same amount here. -
We’ve generally had at least respectable winters in the recent +TNH years.
-
Hopefully, that'll expand East. It appears they're starting to correct from the Trough continuing in the SW. That's really showing the SER Print, lol

Topped out about 40 here, nice sunny day. Now getting a few mood flakes, not sure how since it's still pretty warm out. Hoping for a December 07 repeat here but avoid the massive January (I think) cutter that pretty much wiped out pack almost out -
Which Ensembles ? Just looked at the 12Z GEFS and we have only a couple days of cold outbreaks then when the storm approaches it cuts because of the southeast ridge and no blocking through the 1st week of DEC

EPS is cold To end. That’s a massive vortex in Canada. Would be nice to get some NAO ridging. -

Negative to neutral NAO and PNA to just cooperate.

Need Neg NAO and that all important strong HP in southeast Canada anchored and a weakening of the southeast ridge - storms will cut west of us before this happens........seems like this is repeated here every year over and over - we all know the routine...........

2025-2026 ENSO
donsutherland1 replied to 40/70 Benchmark's topic in Weather Forecasting and Discussion
Several things: 1) There remains a lot of uncertainty how the stratospheric warming will propagate. Propagation could be a big factor in prolonging/strengthening or bringing back Atlantic blocking. 2) Even as stratospheric warming often (not always) propagates favorably to build or prolong/strengthen Atlantic blocking, one should not immediately dismiss hints of evidence to the contrary. Confirmation bias is bad for forecasting. Such evidence exists e.g., here's the AO forecast from the EPS 46-day forecast: Although the below table talks about considering climate change-related impacts on forecasts, I highlighted the section that relates to how and why confirmation bias skews forecasts: A systematic forecasting framework allows one to acknowledge such evidence while avoiding rash decisions from model noise. As I don't have a crystal ball to have 100% confidence in whether or not the above AO forecast will verify, I have made a note to continue to monitor developments. Needless to say, there is more to it than such a framework. Each scenario has clusters of outcomes (not discussed above). It should be noted that such frameworks don't guarantee accuracy, but they do reduce the risks that can otherwise lead to bad forecasts, especially when one is dealing with timeframes over which model skill is limited or worse. Finally, the 11/22 12z guidance has reaffirmed the December 1-10 idea. Indeed, more than half of the 11/22 0z EPS ensembles suggested 1" or more snow in Detroit and Toronto (a good signal for measurable snow prospects from this far out). I expect those figures to hold up with the 12z cycle. -
Its not guaranteed but the signals are looking good. Ensembles are still showing a favorable pattern. Op runs will still flip flop
-
Starting when? Favorable for cold outbreaks is a guarantee - Snowstorms are not a guarantee YET IMO ......Need blocking to set up
