If we go into a super strong Nino, then it's going to be tough to pull off anything resembling a classic winter, imo. A more borderline moderate/strong Nino wouldn't be ideal either, but you'd rather roll the dice with that compared to a stronger one.
If we follow a typical Nino playbook progression, then the odds of a better stretch of winter wx would tend to be later on in winter when the Nino is weakening. December is often a bit hostile or an outright disaster in stronger Ninos, though not always.
