@donsutherland1 @bluewave The persistence of this multi-year La Niña event is just astonishing. Looks like a big restrengthening is on the way over the next several months, thanks in part to the strong -IOD event helping to drive the next burst of very strong easterlies and subsequent upwelling kelvin wave. The latest ENSO forecast doesn’t have region 3.4 going above -0.5C until March/April:
-
@bluewave @donsutherland1 Looks like a healthy +QBO event is taking shape:
-
Very interesting stuff. Looks like the +QBO is starting to take shape. Going to have to see what effect the volcanoes, +QBO, increasing solar and La Niña will have on the stratosphere going into winter.
-
I think it will be an interesting forecast. I’ve seen some experts saying we currently have a volcanic stratosphere. Also looks like rapidly increasing solar and +QBO taking over by winter. When you add in the very rare 3rd year Niña, record -IOD and the very persistent -PDO/-PMM states, it should be a very difficult winter forecast coming up
-
The new CANSIPS is out:
-
The models are showing it going cold-neutral during the winter (J-F-M time frame). They don’t bring region 3.4 above 0.0C until around March. The difference between a weak Niña and cold-neutral winter is negligible, would be same result as you showed. The trend going forward right now is definitely for the La Niña strengthening going into fall at least however….
-
There is also no letup in the La Niña. A rare triple La Niña looks all but certain now. And the -PDO/-PMM mode continues unabated, the -IOD appears to be doing its dirty work. This Niña is extremely well coupled with the atmosphere and yet another period of big strengthening looks very likely:
-
There aren’t going to be a lot of analogs to go to for this upcoming winter, we haven’t had very many 3rd year La Nina’s
-
If the atmosphere is in fact coupling to the -IOD, expect Niña strengthening coming up in the next few months:
-
Looks like yet another JB predicted Modoki El Niño epic fail incoming….this would be the 2nd year in a row. You’d think the guy would just retire at this point lol
-
Congratulations
-
@bluewave @donsutherland1Besides the stout Niña, look at how strongly negative the PDO and PMM are. Given the strong -IOD expected, I wonder if we may see an unprecedented 3rd year strong La Niña event?
-
Not only is a rare 3rd year La Niña looking more likely, the models are getting stronger with it….maybe related to the very strong -IOD event being forecasted…..
-
Extremely doubtful that there ever would have been a Niña in 2016 had it not been for that very strong -IOD event
-
Also, going to be +QBO assuming a normal progression
-
This is going to be a very interesting year I think, not going to be very many analogs…possible very rare 3rd year (Modoki?) La Niña, possible record -IOD event, likely -PDO/-PMM continuing as well as record warm Atlantic SSTs along and off the SE coast also likely to continue
-
Yes, if the models are correct, this -IOD event may be one of the strongest in history, possibly even the strongest
-
Continuing to look increasingly likely that we see a very rare 3rd year La Niña this upcoming fall and winter. Looks to possibly be a Modoki La Niña taking shape:
-
Going to be a rough 8 months coming up for you until December then I guess
-
Snow isn’t getting anywhere near the I-95 corridor tomorrow
-
Yes, a 3rd year La Niña is starting to definitely look likely:
-
My allergies are the worst they’ve ever been in my life. It started the week of St. Patrick’s Day and have been relentless ever since. My allergist just had to change my prescriptions yesterday afternoon
-
Pretty good agreement among all ensembles now that the pattern breaks come mid-month. It may get quite warm mid-April and beyond with that SE ridge flex. I have a feeling we are in for some early season heat come May
-
Yep, even for the 40’s-80’s colder time frame, April, 1982 was very highly anomalous, a true fluke month
-
Thursday has some scary looking soundings for parts of the area. We may be in for one hell of a severe weather event
