This.
Now what I remember and what actually happened may be two different things, but...
Growing up in the 70's and 80's, it seemed every forecast for a sizable storm included the words "blowing and drifting". And I remember it seemed very cold air masses would follow those storms. For instance, if yesterday's storm occurred 40 years ago, it would be in the teens today and everything would be a frozen block of ice.
As great as 2009-10 was, I don't recall it being particularly cold after those storms. Even the blizzard of 2016 didn't feature any remarkable cold afterward.
