Huh - your reading into that wrongly.   It's not statement of fault as to one's particular perception on things - it's fundamental.  There is "more snow" in a 10:1, 10" result, than a 20:1, 15" result. 

 

Ok yeah... so there's still more snow in a 5" glop fest (say 5:1) than there is in 10" of 12:1 snow.

Kevin nobody is weighing the GFS more than it should be. But, to just not look at it would be beyond stupid.

 

We don't have wildly different solutions from the main models at this point anyway, so not even sure what the big fuss is other than Tolland gets rain on GFS...and also gets some rain on the Euro and GGEM. They are all agreeing quite robustly with eachother for a 4 day prog. There's small details that are different but its not like the GFS is tracking the low over BOS while the others are over ACK or the BM.

The jackpot fetish is already rearing its head. All of these solutions still give plenty of snow to N CT/RI after we rip a dynamic gap in the column.

Go look at 12/9/05 on Narr. Tainting to the Pike then boom. At any rate great storm coming up. Hopefully this thread gets off its myopic head and we can discuss the entire region.[/quotes]N CT was all snow in that one. There was no taint.A much better analog is the 2 nd storm in the Dec 96 double barreled nor'easter s

The bigger issue is that although Kevin is a great kid and is fun to hang around with, he's completely wrong in his assessment of the GFS this winter.  His core argument is just not true. It smoked all guidance during the 30 to 40 days prior the blizzard, on enough (few) occasions to accept that there are circulation paradigms that it can perform with superior results.   

 

Now may or may not be one of those times.  

 

Namely, as I have hammered this in the past, the GFS has a progressive bias, as is also noted by NCEP and their tracking.  When the flow is in fact verifying fast, ...logically, there can be some safe assumption that the GFS would perform better during such times.  Ding ding ding - that was the case in the month prior to the blizzard.  The flow was in fact fast, fast, fast, and the GFS kept telling the other middle range guidance, but the others just kept trying to wind up bombs on their respective D5-7 ranges.  The Euro was hugely guilty of phantoms during that time, too.   

 

Anyway, now we have kind of split Hadely going on... disparate characterizations about the hemisphere as a whole - at least on our side of the Globe.  The flow is entering a tendency for blocking above 45 to 50N latitudes, while it is remaining fast along the kiss points of the subtropical ridges and and westerlies.  It may not be totally safe to take this measure, but "intuitively" that's sort of even money on which run will successfully assess matters.   

 

But this business about the GFS not being useful this winter is just not true.

If the debate on what is and is not a snowy pattern were scientific - one would have say that 4 storms at 10:1 is a far snowier pattern than 4 storms that dumped 15" at 20:1;  the former has more "snow" in the snow pack.

isn't he older than you?

FWIW/FYI, GGEM changes all of CT over to all rain:

I normally hate to use those ptype maps as they often obsess with warming the sfc and BL but in this case they are probably decent as the R/S on there follows the mid-level warm nose fairly well before we see a dynamic collapse to the SE

An interesting note on the GEFS is that the warmer solutions are all weaker with the low...the solutoons that really bomb the low out all have the mid-level temps collapsed to the southeast...dynamic cooling is definitely the dominant factor on those solutions.

Every model gets taken into account this far out. Euro tainted your ass for a little while.

Just about every mid-range model taints CT for a while.  It may or may not happen that way.  But it is a reasonable suspicion based on a basic synoptic meteorological assessment of the setup with a resilient primary in the upper Lakes and a near shore SLP track.
