Lurker on this thread, originally from College Point Queens, been working at NWS Chicago since 2010. Jealous of this storm, as it's been exceptionally boring out here and big snowstorms like Superstor

I think you’re going to see a correction back southeast today as the arctic airmass that’s building into the region throughout the day begins to get ingested into the models.  The temp drops thro

So we're about 36 hours from the storm and we generally have no idea what's going to happen?  And by that I mean, who is getting shafted, where the heaviest precip falls, is there a dry slot, is there a jackpot zone?  Is that fair to say.....IMBY I've had anywhere from 6 inches to 29 inches the past 2 days of runs....

Pretty much the case for every major storm

Yup this is a nowcast event for I-95. My call is 5-20". That should about cover it haha. For trenton I'm calling 8-14" but that could easily fall apart. The mixing line cutoff is going to be brutal.

I don't think I've ever seen a dry slot location modeled correctly 40 hours before the a winter storm. If you see one modeled over your house on one of the mesos 12 hours before game time, then there may be cause to worry. These are very dynamic events laden with moisture.

It’s a nowcast event everywhere given how tight the gradient between the mix line and the sharp northern cutoff is. I’d agree at this point with 5-20 inches area wide as a forecast

Gfs looks good for us, lock it in.

Only consistent model. The Canadian suite it like watching a show stoned and throwing darts. Worthless. This is going to be ugly for a lot of people who don't live at a higher elevation if the GFS is wrong.

Not good trends for those of us near the coast tonight outside of the GFS, good for the LHV and northeast PA. If the Euro shifts north tonight, could be trouble.

Trends aren't good ?

The GFS almost always consistently does this with these events though, it’s just consistently wrong .  The Euro has probably been the most consistent of all minus that wild 06Z run it had last night

The cmc had been very consistent until this run bumped a bit further west
