You mention the Jan 78 blizzard, I was under that sphere of endlesss snow here along the Jersey shore back in that storm.
Can I expect more than the 2-6" here along the Ocean County coast. Especially if it does that repeat loop of 78'.
I also understand the storm back then had all cold air with no precip issues. This time around it is a more typical Nor'easter as in rain to heavy snow.
