I was checking dry Oct/Nov periods and since 1950 all 5 combinations of Oct and Nov that were well below normal (<1.5" precip/month) were in Nina or negative neutral periods. So, it would certainly argue for an increase in precipitation later in the month.
(1964, 1974, 1998, 2001, 2016 - winters were below normal precip and snow, but again, all Nina-like)
