JMHO, but I think anyone who actually said this winter would rival the winters of the late '70s was probably injecting a great deal of wish-casting into his predictions.

Sure, there were/are some climatological similarities between this winter and one or two of those late '70s winters, but to say that this winter would rival those? That would have taken an extreme leap of faith.
The reason we didn't see much moisture in the first two weeks of January is because the same northerly flow that is required to deliver those temps to us is a dry flow. In our region, we rely on the Gulf to provide the moisture that powers storm systems. If we're under an arctic regime that doesn't relax long enough to allow the Gulf to get involved, we're going to be mostly dry with the exception of an occasional clipper system. Sadly, the only time that happened in that 2-week period earlier in the month, we didn't have the energy in the right places to capitalize and wound up with what was, in effect, a clipper.
Those are my thoughts and I'm sure others can expand on them and do a much more thorough job explaining the dynamics of what we've experienced thus far this winter...a winter which, I might add, is no where close to being over.
