I also have noticed a later trend in closing off H7 which is usually not great for those wanting S+....esp in SNE. Hopefully you guys on the line work out for the snowier.  

Yes. This is why I strongly favor GFS track/intensity.

The mesos seem "bend back" happy. Not sure if it's a convective feedback issue or what, but the UL capture doesn't happen until east of MA.

Why? GFS is often the warmest in the boundary layer.

Well, first, I wasn't expecting it to leap-frog them like it did.  Secondly, see my 'first'.  :)

 

The Canadian has trimmed back a little from it's 00z run.  It does provide a widespread inch or two over the weekend fwiw.

If I was chasing, I would probably choose a place like Jackson, NH or Bethel, ME. They seem to be in the "safest" spots for getting hammered.

 

You could ride the line a little more in a place like Ossipee, NH over to Bridgton, ME...and might be rewarded with mega totals just west of the sloped front there, but you risk being exposed to some of the northwest solution outliers dryslotting you and even tainting for a time.

Does the capture slow it down at all?  I hav noticed the timeframe for snow to begin and end is longer than it was yesterday.

As much as I am disappointed not being able to head to Winni....I'm also wondering if that's a better decision since it could be a wet snow. Don't need power outages. Hopefully Brian's chicken coop has an added support beam.

My few miles west of Brian might help me if these west solutions come to be.  But wouldn't this kind of storm have wet snow for a while but then end as 2"/hour powder?

Yeah very well could at the end of the CCB as temps drop below 850mb.  

I was assuming, that if I am to exceed 15", it would be 8-10" of wet snow at 9 or 10:1, followed by 12-15:1 powder.  Great for base building, given that we only have a 3" base left now.  Bummer that you can't get north, but I'm sure  you'll have your chances in January.

I got a new inverter generator so I'd say power outages are very unlikely.  Hopefully nobody in the area bought a snowthrower.

meh, don't want to start any sort of debate ...but, i grow weary of reading GFS-bash posts when from my own experience it hasn't exactly failed this cold season, either.

as far as this system: personally, i bought into the non-hyrdrostatic forcing on this a bit more than i normally would, because i focused on an intense appeal of very compressed isotherms in the 850 mb along the del marva.  perhaps proven wrong - we'll see in the end -- but there are plenty of examples in history where that sort of anomaly fed-back;  having fast and small cyclonic rapid intensification collocated with excess difluence running over top was/ is not unprecedented. 

It just may not transpire in this scenario when all is said and done, but if so... this would also be another reason not to bash the gfs.  just sayin'

Well I'm about 25 miles north of Brian and at 1100 feet.   Maybe more of a 28-30F snow up at my elevation.   I saw Jerry forecasted only 5-10" for me since I'm half way between Brian and MarkO.  Definately don't need power outages so hope my elevation helps with a bit drier snow.   I'll guess 13".  For many of the big storms I get that number!

What types of expectations to folks have for winds throughout the region?

Inland it doesn't look like a ton of wind initially, but there is signal for an increase in the boundary layer depth as the backlash CAA starts towards the coast and heights collapse. Inland maybe gusts around 40 mph the way models have trended, but closer to the coast could be sneaky higher wind.

Yeah figure 36 hrs at 1255. I really haven't seen the Euro change in 5 days, pretty much ignoring everything else trying to play catchup 

The euro is coming back down I think from some of those earlier amped up solutions. That's a big deal for CT. As usual, some sort of a compromise is the way to go in forecasting, with the understanding of model biases like GFS low level temps.
