They say this winter will be the warmest in history

They say this winter will be a record-breaking "Super El Niño," going beyond just a strong El Niño.
I suggest watching a YouTube lecture to understand what El Niño is and what its impact entails
(it is one of the core phenomena of global warming).
To summarize just the conclusions:
1. This winter will be the warmest on record.
2. Frequent light snow/rain (somewhat like squalls).
3. Beware of occasional extreme sudden cold snaps.
That seems to be the gist of it.
It looks like it will be a winter warm enough to actually feel the difference.
