I am locking at least another 50 mi., or perhaps more (100+?) s/e trend on the gfs.

The uk and rgem staying in the ballpark is good. I'm hoping the euro comes NW a little, that'd give me confidence. The other times when we had some unfortunate systems all models bumped se at this stage to varying degrees.

Uk edging a bit NW, and rgem looking good probably signals this is going to be different and the euro will edge NW.

This move was totally expected, think we said as much on page 1. No bad news here aside of the nam which is tossed

I don't like that look since the screw potential is so high with that weenie enhancement to the QPF. Unless you are at 1000', you are on the outside looking in without the big lift.

I don't know why, but when I look at the gfs I have flashbacks to 2/10/10 in terms of qpf placement wrt 500/700mb low placement. I see why the model is doing it, but I do not trust it.

If we end up 35.2F and pounding rains, so be it.  00z GFS cold at H85.  I'll take my chances for a heavy wet warning level snow.

The reason why this is doing this in this run is because there is a significantly stronger N stream closed vortex being inject into the back side, and it not close enough to phase, so the natural result is that it kicks - it's a new feature, so I would urge caution on this run.  

 

Hopefully folks will listen to this instead of just getting pissy and knee-jerk reacting.

As long as it doesnt get squashed on the north side by confluence, it should be fine. Dec 1992 gave like 4 inches of qpf with a similar placement of the ML features...Feb '10 screwed us...I think a lot has to do with how robust the ML circulation is...if you look at Feb '10 you can see how squashed it looks on the northern side on the maps versus a storm like Dec '92.

 

I don't expect Dec '92 again, but I think the firehose is far enough north in this one to do damage...assuming the Euro can bump NW a little more. If we get a Euro solution at 12z verbatim, then we'd see uglier results. (but still prob more precip than Feb '10)

We should do karate in the garage.

It's odd to me that the gfs had so many adjustments so early but then again maybe I shouldn't view it as odd as I figured it was off its rocker. Correcting may be a better word. The rgem has the main ULL in a good position with the northern energy coming down. The negative sentiment is partly the crappy nam which should be ignored up here.

First sentence is from step brothers (movie).. I am saying we share the same idea not challenging you to a duel. :)

The thing is, that firehose is everything. 50 miles se and it's some rain and snow with gusty winds. Walking a tight line. The storm acts like a normal low over the MA and then we have to hope that firehose (which is real) makes into SNE perfectly. I the relying on that. Could it happen, yes, but it's more of a gamble.

I also think there is negative sentiment in that the GFS didn't get even better...people saw this thing ramp up for like 4 striaght runs and now finally it is starting to sober up. Its always a bit of a buzzkill to see a model finally come down off the most extreme solution desired.

 

We can tell people not to expect 20" of snow, but its hard for them to see those model runs and not seriously think about it.

I didn't buy those runs at all, but I don't like relying on the dynamics...it's just a tough gamble. Hopefully the euro comes north. I'm just a little skepticle still.

In the most stable solution scenarios, the GFS is known to insert a run or two of 'whaaat'...   Not sure why the GFS is obtrusive with that feature suddenly, but we can't say this is any beginning of any capitulation - that's absurd to me.

 

1  this feature isn't featured in any other model type, like it is "suddenly" and "inconsistently" on this run.

2  in its absence, the result is still the same; though, it's still meaningful, albeit middling in this run.  

3  if the new features exertion verifies, you can't blame the GFS, erstwhile, because it would be the first run that saw it.  

 

But I can see the clan just default scapegoating as usual.

Well there is no other option for the coastline, is there?

And despite the pissing and moaning.that it didn't snow the 18z 4 inch qpf boms it gives 2 inches ORH east, 3 BOS east, 1+ pretty far north.

 

Yeah...you'd think this thing missed. :lol:  

 

Everyone take a xanax and get a good night sleep.  

 

But I agree with Will's observation.  Always a buzzkill when the most extreme solution comes back to reality (a bit)  It could easily ramp up again at 06z.

Not to complicate matter further, but that is not really true, Will - look at the eastern GL ULL in this run; it's obstrusiveness is so new that it's questionable whether that is real - again again again, without it, this run is really just like its predecessors.  It's may be more "drunk" in having suddenly introduced this... 

 

But I agree - people have an idealized solution in mind, and when model runs start going toward it, they get all giddy but just can't wait to woe-is-me when a run arrives that angles less.

Yeah agreed. For all the issues with the gfs at least it's mostly predictable at this point in this winter. The NAM is still our Gary Busey but at least it's whacked out enough usually that we know we can toss.

Long as the ggem and euro stay in the area, hopefully with upticks to both I think we are in good shape. Shame it's not a little colder, this could be quite memorable for some of you with this inflow and duration
