Not impressed with the GFS and NAM tonight. Not interesting to me in the least. Both models run the risk of leaving us in a situation where the u/l unravels and we're left with a patented Ray shredded POS and as Ryan said without a comma head.....

It's early though, not worried about any of this until after the 12z Tuesday. This is all semi fantasy land. Wouldn't be surprised to see it run over us, or end up a sheared mess SE of the BM in later runs.

Euro....take me away.

Did anyone do a cross section analysis?

This looks like a big 6 snow mass in a narrow strip from NW of HFD to ASH and 20 or 30 mile either side of that axis to me. Even BOS ends with a 1/4 mile vis in wet snow for a couple of hours.

Relax you snow geese - the woe is me is a bit forced here.

Do you think we have to start thinking about widespread power outages in that narrow strip again? I know the leaves are gone, but It doesn't seem like this snow will be the driest snow considering the air mass that is here now. Especially if its a quick hitter like 10.29

Holy Crap... the GGEM crushes the interior with a 995 low just inside BM... Ukie is also an interior crusher again.

Doubtful. There is an extenuating circumstance in that some debris still lingers precariously elevated around the infrastructure, perhaps accentuating that potential, but nothing nearly as widespread.

It can only come so far though... I'm not worried about a track being too close - we've had better turn out from closer passes!

Well yeah, the PV will prevent it from coming through BGM or ALB...but we don't need it that far west to give us ptype troubles.

But I agree there is a limit,.

What are the western and eastern limits of the track of the storm with respect to the polar vortex?

I suspect the track is within 50 miles of verification in the models - figuring the GFS comes bit NW and the NAM is either on, or settles slightly; what we're getting at is if the cold will be deep enough, if not, will dynamics be sufficient.

Real real close call here!

Problem is that it's coming NW because the lead s/w is tracking further NE. So some areas don't even get into the cold air first. The warm air isn't from WAA ahead of the storm, it's from the previous airmass. Someone will get a decent snowfall, but it will be in a narrow stripe

This has always been the huge issue with this storm.

This is what we have to deal with in a threat during a garbage pattern...have to hope for the best.

This actually could have been a significant storm (large area of 6-12") if we had a -NAO in place.

Dang. haha

Yes blocking would probably make this a legit MECS threat with even an outside shot at a HECS...but instead we are hoping for a quick hitter that dumps 3-6" and maybe some spots getting more if lucky.

But still a lot of issues in this ugly pattern.
