And that is going to take a strong NS wave to dig southward further west. GFS does this for the next weekend event, while the Euro misses- it does it with another piece of NS energy a couple days later, but yeah as depicted it's a warm storm with low pressure tracking to our west.

You wonder if the Canadian and GFS are better at handling the NS energy and therein homing in on a threat quicker than the Euro?

I see what you’re saying. It doesn’t have to completely phase, the NS just needs to dig enough to pick up energy from the SW. the CMC does it too. Euro completely misses by hundreds of miles, and then completely phases with a second NS wave. Drastically different solutions, very low confidence forecast.

Exactly. Need some interaction to get that energy involved. What the GFS does here is ideal-

the ECMWF actually made a pretty drastic shift towards a more potent NS. hopefully it isn’t just a blip, because it’s much more similar to the GFS than 00z

There are so many shortwaves embedded in the NS flow its chaos this far out. The character of the western ridge at specific times is critical too- the axis, whether its more amped or broader..

The Euro otoh progresses the ridge axis further east with somewhat lower amplitude, the NS energy in the flow doesnt dig south enough, and it keeps the southwestern energy buried underneath with no interaction.

Well, I see we are truly back to the good old days with Euro burying energy out west and GFS sending the energy out all at once to create our snowstorm.

Looks like a step in that direction. See what happens over the next few runs. The GFS will probably come up with completely different evolution lol.

Are you looking at that energy over Alberta/Montana? 

Its so chaotic its hard to pick out the individual pieces

yes, the piece over Western Canada that wasn’t really there at 00z

I figured, yeah. Lets hope it’s not just a blip, but a start of a trend. I think canadian has a compromise between the two camps

December 19, 2009, we had 23.2" of snow and the SST at ACY was 53f.

Yup. Wind direction matters. You get a screaming east wind and it's sleet city. But turn that into a north-northeast or northeast wind and we're draining cold air from interior New England. Geography matters.

I believe 12z ICON would be good for us... the run ends at 180, but 1037mb HP up top in Canada moving east in tandem with the moisture 

It is a bit slower than the GFS, but it looks to have the same idea.  Definitely not in the Euro camp

Agreed. Slower than gfs, but looks like 6z gfs with how it’s starting to phase the shortwaves.

 Fwiw.  Sterling  mentions next weekends storm in their disco

. Always nice when they finally see what we see lol....

 

"The noted warm up is to be short lived as another shot
of cold advection invades the area. On Friday, area-wide high
temperatures return to the mid 30s to low 40s, with 20s in the
mountains. Another system may loom next weekend, but details vary
greatly between model solutions".

Yeah, they’re seeing the same thing we are. Just a very low confidence outlook at this point. Let’s hope the gfs/cmc trends this morning converge and the euro caves.

Gfs looking totally different at uppers at 132hrs compared to last run. So there’s that…

Not loving what I see on the GFS through 135, less energy diving down from N/S and Baja energy seems weaker more positively tilted.


.

Yup euro wins when it comes to getting trash. It shows a snow storm at 180 it’s wrong but a cutter boom lock it in lol
