It's also very easy to pick 1 element that's the same. North Atlantic

Has there been any research into looking at past weather patterns and
perhaps assigning some kind of "similarity" metric to the various elements
of previous data?

Probably means thay had similar October weather - only trouble is the cold
spell was January - March, and I don't think you can extrapolate for more
than a few days.
