What a huge shift north on the AIGFS

Is that a full phase on the euro?

Euro has snow from Sunday morning  through Tuesday. Heavy snow Sunday Night and then Monday afternoon from a coastal. Still going at 144.

Updated good suite of forecasts for those enjoying the snowier outcome

Ceiling is quite high if we can get western energy to fully phase in. 

I think even if we don't we're probably looking at a 4-8" type system at minimum

Inching North with the 0.5 line

The 12z Euro only did a partial phase and still pulled off a MECS. The only thing we can’t have is those two pieces staying entirely separate. Literally any interaction and we get at least a SECS.

Setting our goalpost. Gfs about as low as we probably go. Euro highest

NYC and surrounding areas would most likely see over 20 inches passed 144.

At h5 we’re not too far off from some pretty big solutions.

Kuchie though, and snow map 5 days out so grain of salt, salt mines worth of grains of salt.

EPS made the same shift towards more phasing and now has 0.75" liquid to NYC

Agree.  The pictured event took place with temperatures between 28 and 30.  It caused widespread power outages

There's a pretty high floor with this system because it's so large with tons of moisture and very cold air but the question is the phasing which would create a much higher ceiling. This doesn't feel like a thread the needle situation that we usually see in these parts with an all or nothing scenario.

Can you post the non kuchera version. Or just QPF? 

[brooklynwx99]

.75 with favorable ratios would be great. I’m not buying the kuchera maps showing over 20:1 ratios but to each their own!

Probably 13-14:1 at best. Ratios aren't about surface temperatures.

100% agree - not even worth worrying about. I’m just looking at QPF - easier for forecasting and consistency. 

[North and West]

GFS made a big move north.  Wagons North.  Trends aligning favorable

A cutter with a 1050mb Siberian High and unmodified arctic air/confluence pressing down?! Lmfaooo I’ve seen it all now. The threat is suppression, not cut, not even close
