My (correct) point is, nowadays when a winter month has a lot of precip, it’s almost a sure bet that most of it is rain. But two out of the three past winters you mentioned had wet months that were mostly snow. So in the past, an anomalously wet winter month could be rainy or snowy.
And snow has not been the predominant p-type this winter, lol.
Also, we were talking about January, why bring in December? Try to keep up.
