I've seen this play out many times in my experience on the eve of big storms. The Nam has that one bonkers run that you cut the totals in half to get a true depiction and will correct itself by 12z while the rgem and GFS are too conservative and will usually correct itself upwards by 12z.

As usual, blend them all and I think a good forecast is 4-8+ well north and west, 8-12+ for NYC and immediate burbs, 12-18+ for Nassau, 18+ for Suffolk.

Agree 

Banding in these storms usually end up further northwest than modeled. Have to watch out for that.

The inch of precip line on the Euro is now touching NYC.

this snow map now looks like the 12z NAM run that got everybody excited. In fact I believe it's slightly more. Nam reduced the double low look on 6z and we got the jackpot over NYC... hopefully the Euro keeps correcting towards the NAM from here on out.

Who cares if it's going to melt? Just have it happen lol.

Agree, it’s got to happen first.  But i think it’s fair to make longevity of the snow part of the conversation.  Would be nice if the snow sticks around for more time than we spent tracking the storm!

Euro still has an elongated low. If that's wrong then these totals will go up.
