2026-2027 Record-breaking El Nino

This will couple more than 2024 at the height of the cold phase. -

ECMWF hints at this, though I think this is exaggerated....likely closer to the coast than this. That is a resolution issue...like when the GFS places the CF near ORH a few days out from a storm.

Roundy's stuff favors W Canada. -
I would do okay, but could def. see it being an ORH season...they have had some uncharacteristically skunkish seasons of late....gonna see that regress.
-
CFS January rendition would make some fun times for WOR folks....Miller B-East, much?
-
Has December near normal surprisingly. Is it a bit too cold? Probably....likely underdoing the magnitude and arial extent of that Canadian ridge, but I don't think this will be a bottom-dweller season in terms of snowfall.

Here is January:

Absolute same page....128-495 CFs. Megalopolis Storm CF was right over Wilmington.

This is the European monthly depiction of precip anomalies overlaid with temp anomalies for the month of Feb. Euro is my preferred solution because it doesn't have the zonked Modoki look that the CANSIPS and JMA do....that is overdone and crap. But the Euro simply evolves the El Nino in such a manner whereas the warmth gets pretty evenly distributed..pretty basinwide for winter. You drop those type of precip anomalies, I will gladly take my chances with a +1 temp anomaly at this latitude.

Augdewst 2026: Summer's Last Stand
40/70 Benchmark replied to Prismshine Productions's topic in New England
I do, but not during the summer....I consider that before the final write up....I go back and compare summer composites to find fits to the current year. -

Yea, same page...I think this is a good assessment. I initially didn't have time for a deep dive and just looked at the IRI, but I think the dynamical data has over adjusted and is too cooked...I'd go statistical suite. I usually kill it with ENSO forecasting, but being in uncharted territory like this makes it more difficult to pin down a specific range, despite obviously knowing it will be intense. -

@GaWxI edited these down after really looking at it more...I have put most of my energy into the extra tropical Pacific of late. This is consisted with the max rate of growth observed form this point forward, which was in 1982. -

@Stormchaserchuck1How does this composite look now? I tweaked by subtracting the 1941-1970 climo period to wash out a lot of the lower heights and accentuate the positive anomalies in an effort to better capture the changing climate.
