Monitoring first regional significant winter impact event. Magnitude likely tempered. At this time NE PA/SE NY and SNE primarily. Jan 7/8.

If I could lock it I would.

This was the feedback I was looking for and hope to recall in future 

There is a reason why there is so much concern about convection ruining phasing dynamics in some potential high end bombs off the coast. Threading the needle isn't easy. This setup seems "messy" enough that boring background dynamics should win the day and get this thing up the coast without convective issues.

The gfs went south a bit, but the Canadian went even more north. Low is also deepening to the high 980s

GFS IS 988 Too.

It’s putting all that emphasis on the lead short wave, which it holds the identity of longer… It has virtually no interaction with the second wave

Was a violent but shorter pounding it seemed . Was over by 1pm into E mass

18z-0z panel had nada precip except .1 over Eastern half Essex county

Wow the Canadian is a pummeling here. Holy smokes. Starts as paste and gets colder

Probably delusional but it would get mid-level magic into CNE.

[NittanyWx]

Fun to see the 3 operational models all have different ideas on how to handle that trailing vort interaction.

 

First bit of sampling out west and that's become an increasingly interesting feature. 

[78Blizzard]

Gfs bombing out late gives the outer cape the good stuff.

[WinterWolf]

The CMC doesn’t really put much emphasis on the trailing wave though.  Everything else seems to incorporate that trailing wave.  CMC behind some on this evolution?

Yeah, that’s a burial. CNE absolutely gets in on it with the low that far north.

The front running wave is much stronger on the GGEM so it never really allows the trailer to crash the party. It keeps the downstream ridging in front of the trailer to a min. But when the front runner is that potent, you still get a big solution.

Our current weather paradigm over the past decade says, always plan on the system lifting out faster than modeled.

[Typhoon Tip]

Yeah, I don’t know… With a growing consensus heading another direction vs the CMC’s track record … that’s a bit of a buyer’s beware solution

Lynnfield did well. They must have had  18 easily. I saw pics from my wife’s family who lives there. 

North shore in laws, rough.

Agree. The good news is though, there seems to be multiple ways we can get it “done”, which is a complete reversal of the past couple winters.

Thanks Will, but I understood that part about the leading shortwave being strong, my point was that the CMC isn’t incorporating that trailing wave as the other varsity models seem to be, and perhaps it’s a flawed solution due to that fact, and perhaps not prudent to take it to seriously because of that?

More of an omega block on 0z versus 18z, should be more tucked

Congrats guys

Went from a few inches down here to rain. Still waiting for an inch of snow. Will be near 700 days soon.

Idk how u live in NYC, regardless of snow. 

[Thunderblizzard]

The GEFS seem like a pretty solid improvement from 18z.

[MuddyWx]

I’ll take that from the GEFS

Much better handle than the 12z. Maybe the new sounding input influencing?

Some massive hits scattered in there

Amped.

[RUNNAWAYICEBERG]

Quite a few nam like solutions there. 

[MuddyWx]

Improvement for sure, juiced up from 18z

Some rainers for sema too. I guess ya gotta play with fire if you want the high end outcome.

That’s impressive for a mean. 

[brooklynwx99]

GEFS is actually steadily trending towards the kicker S/W phasing with the trough and creating its own axis of PVA. this would have pretty big implications for you guys and even down here into LI/LHV/NNJ
