The writing was on the wall about a week to 10 days ago when the models bailed on the big cold. It's just not that cold. Today is considered "cold" and it's around 35 for the high which is roughly average for this time of year.... North American snowcover is at an all time low and the Great Lakes are warm/ice free.
Hard to say for sure, but there's been other long term periods of relatively snowless winters. Regardless, we are clearly into one as snowfalls the last 3-4 yrs have been few and far between.
