More on the not mild 1877-8 in much of the E US:

NYC using 1869-1900 for normals

Dec 37.4 (+3.2) AN

Jan 29.9 (-0.4) NN

Feb 32.3 (+1.2) NN

So, DJF +1.3 NN with only Dec warmer than normal and even it wasn’t a torch

Parts of the East had their lowest snowfall of the 1800s that winter.

The big story during the 1877-1878 super El Niño was the warmth in the Upper Midwest.

It’s an example how  really strong El Niños can sometimes have their warmest departures in February. 

While we don’t have the 1841-1870 climate normals for MSP, I used the earliest available 30 year period.

The departures for them that winter would have been like if December 2015 had run through February 2016 in the Northeast with no pattern reversal.

MSP 1877-1878 

DEC….+14.5

JAN…..+9.8

FEB……+15.8

Here comes the next monster WWB

@Mitchnick Which models are you looking at that always show the trade winds coming back? Because you’ve been saying that for quite awhile now and all we’ve seen are record breaking WWBs, westerlies and a complete trade wind reversal

That's what the Cfs2 was showing over 3 months ago when I posted. I was just the messenger. Obviously, Cfs2 forecast, updated multiple times a day, changed.

I was just looking at that stuff... 

According to CPC most recent power point,

yet the present NINO 3.4. regional anomalies ( found here:   https://climatereanalyzer.org/clim/sst_daily/?dm_id=nino3.4 ) are already floating around +2.00 C.   So, either their CFSv2 product is less accurate as a predictive use ( by over a whole deg C ), or... Climate Reanalyzer's data is suss. 

I don't really care to get into that ..per se, I'm really just more interested in general with the comparison between monitoring vs modeling: where are we?

Daily Cfs2 plume charts are updated daily and hyperlinked to this site; past half way down.

Unlike the very mild Feb 1878 in the upper Midwest, the E US’ warmest month of that winter was the fairly typical El Niño warmest Dec. In contrast, Feb was only modestly AN in a good portion of the NE to NN in the SE. Jan was NN to BN. Jan-Feb combined in much of the E US wasn’t mild at all and instead was largely NN (no more than slightly AN in the NE and even BN in good part of SE).

That CFS graph is referring to relative 3.4 anomalies, which are currently in the +1.3 to +1.5 region rather than ~+2.0. Actually, the official relative 3.4 for last week was only +1.3:

08JUL2026         2.6        1.7        1.3        0.5

https://www.cpc.ncep.noaa.gov/data/indices/rel_wksst9120.txt

 The CFS latest 10 day mean prog has a whopping +2.3 for relative 3.4 in August! August will be a really big test to see if the progged record breaking Nino is still on track as that would require a near 1C rise from July! Going back to the start of records in 1950, there has never been a 1C+ rise within just one month. I‘m talking about any month in any ENSO. Will it actually warm that much in August??

Absolutely believable based on the massive WWB about to start, which I just posted about above from Paul Roundy, the subsurface warmth and the new DWKW making its way east
