Storm total snowfall and QPF:

Click to enlarge maps.

QPF clearly over performed even the wettest guidance, in some cases by 1/2" or more depending on the location and model of choice.  The models ticking up the QPF as we got closer to the event start time was clearly on the right track though.

Quick spot checks on ratios and nothing to write home about when averaged out over the storm duration....roughly 8:1 to 12:1 along the I78-I80 corridor and east across the city and LI.  Just did a quick spot check.

I'd have to give a nod to the higher QPF totals for getting storm total snowfall to near or over the high end ranges of the forecast.  If they had been more or less as modeled in the 1 to 1.25" and taking the actual ratios into consideration storm total snowfall would have been closer to the lower end of the forecast ranges.  Just my 2 cents.

Celebrating the anniversary of Feb 5-6 1978. Break out the champagne

That's a deeper low than in 1978, but there was something like a 1040 high over Quebec in 78.  The closest thing I've seen to the winds in 78 was 12/26/2010, but we had at least twice as much snow in 78 vs 2010.  Only about 12" here in 2010.

I suggest checking out the thread @Typhoon Tip started in the NE forum.  Classic signals are aligning and he’s all over it.  And has been for a few days already.
Mods - is there a way to have a thread exist in 2 forums?   I am guessing no - 

".. a very special crossover episode of American Weather"

While it looks good, I go back to what is always said, you don’t wanna be in the good zone this far out. 

Generally I would agree but all the models have a big storm in the vicinity and the pattern supports it, plus we're not in fantasy range anymore. Also, there have been a few KU's in the past that were locked in on the models a week out. Of course plenty could still go wrong but it'll be a fun week of tracking at the very least.
