    I guess this will depend on the track and other factors as well.

    On the most recent 3k NAM, here's a depiction of the coastal front at its most inland advance before it starts to crash back south and east. Pretty decent amount of areas puking snow at 33 degrees for at least a few hours. Here's the sounding for Boston at the same time.

    I feel like the NAM has a tendency to bring that coastal front at the surface in a little farther than reality in these types of setups. Move that line about 35 miles SE...

    I'm looking for reasons why this might fail IMBY but can't seem to find any. Perhaps a dry slot or coastal front from hell would screw things up, but I don't see that reducing my total to less than maybe 8".

    In Cumberland? You're golden there.  That is usually jackpot #2 in RI.  I'm in the more worrisome area as usual - the bay is never my friend in snow events.

    No one is seriously considering it seriously 

    The 48HR HRRR is just another map to look at - one thing to consider is that I believe at some point, that the HRRR will be updated and eventually replace the NAM in the future - though I may not be remembering that correctly.  So the 48 HR HRRR is kind of the "New HiRes NAM" in testing mode...

    Lol - GFS most consistent model...tough to go against consistent...EURO may do full cave tonight with sampling better ...GFS will be crowned new king or if wrong EURO says get out of my house...battle Royale here!

    GFS most consistent? Not really...

    Also, I believe (but not 100% sure) that the NAM had same full sampling as GFS at this point, so if sampling was a variable there should have been a similar outcome, but they are rather different at this point.

    Oh, no.. Did they put this on air? Yikes 

    I don't know if that was on air, but it was definitely on their web site, and maybe their Facebook page.  I saw a handful of people re-post it last night and this morning on my Facebook feed, and got a few questions about it.  Clearly some people thought that was the forecast.

    Last winter was my first in RI, and it was a big disappointment. We had one decent storm in early December (10"), but the rest of the season was completely forgettable, and afterwards the only thing I really enjoyed was my ski trips to NNE, which did get some good storms.

    I'm much more hopeful for this winter.

    Nice to see more Rhode Islander’s on the forum. We can all ensure the pain of the snow hole together. LOL...

    It doesn’t. Was talking about ICON.

     

    I don’t think anyone is “wishcasting” here at moment:

    https://weather.us/model-charts/gbr/massachusetts/snow-depth-in/20201217-1800z.html

    Switch  between the models available and tell us which one sticks out like a sore thumb?

    The evidence points right now that the GFS isn’t seeing something the other globals are, including the ICON.

    You sure it won't be the other way around?

    This is the third run in the row that the GFS has done this.

    We have had snow storms where the GFS does this 8 runs in a row, and hasn’t come around until it’s already snowing LOL.

    Of course this could be the solution but it’s in the minority of guidance at the moment.

     

  9. Does anyone ever look at the 768 HR CFS on Pivotal Weather?  Just curious if it's useful for anything.  I know the surface/qpf stuff would be useless, but wondering if upper air, 850 temps, is even in the ballpark on the long range....

  10. This thing is moving fast.  I think 12" south of the pike until you get really close to the south coast of MA and RI seems more reasonable regardless of snowfall map output.  To get more you're gonna need really high ratios.  Maybe that happens, but I wouldn't expect to see accurate modeling of those kinds of ratios this far out.
