GFS and EURO have the same players ont he field as far as s/w go..

The euro closes off the OH valley, VA h5 low and keeps the southern wave open and weaker....

The GFS wants to close off the southern wave and produce from there.... WHAT A BATTLE!

yeah due to the fact that there is 1.5 and 2" qpf amounts for DC up thru all of SE PA and up to NYC I'd say yeah

No doubt about it but I really find it absurd to believe the GFS solution at this point (what is it like 7 days out. lol). We are about to enter the coldest days of the winter thus far and when this storm comes around it is just going to scour that out and give NYC a Noah's Ark rainstorm? Sorry I find that far fetched. Too far out to believe the GFS hook, line and sinker at this point. Obviously it is all about timing, storm structure, downstream setups (i.e High Pressure positioning and whatever else), etc.

the GFS also has that high in Central Canada

at 144 hours the gfs has a bomb sitting off the delmarva, its a completely different solution. Its much slower, so that high could actually build in

its actually like the DGEX in some way as the dgex has a storm coming up at 180

I've seen many times when we are in an arctic blast and 2 days later its 50 and raining so it is possible. Considering the fact however that the GFS hasn't shown anything resembling a storm it would be ludicrous to think this is the correct solution

lol, seriously, worrying about a dry slot seven days out?

All this needs is a slight tap 20 miles east to put the big cities in the jp zone once again. As of right now, looks like NYC is in danger of being dry slotted. I dont recall ever seeing such a wrapped up non-tropical cyclone before on the GFS. System looks tropical.

semantics...its there, it is there at 126hrs.

more importantly, as everyone is looking at the snow/rain that is on the East Coast, what is with that second vortmax just behind the lead vort over eastern kansas at 138hrs (it is there before and after)...obviously what the GFS spit out here is chewed gum...it CAN NOT be right...i'll bet anyone that the h5 map will NOT look like that 120 hrs from now, which would lead to a potentially vastly different solution once corrected.

DT basically said on his FB page the same thing I have been all week...weak low and everyone is good other than maybe coastal regions in the southern MA...strong low its over for everyone except higher terrain inland.

so we should be rooting for a small amount of snow instead of a boat load of rain then??

(this is not intended with any sarcasm at all)

You'll get a ton of snow in this setup with that high there because of the overrunning...a 100mb low would produce a very big snow event here while a 985mb low is all rain....the 00Z GFS badly undestimates the front end snows still...places like NYC and DC would probably see alot of snow before the rain changeover based on the 00Z GFS but the model just is unable to see it this far out.

It's a nice rainstorm though. Maybe if it slows down, high pressure can build in and keep us colder but who knows at this point. This could be the snow pack killer, but we'll probably see more snow afterward even if we do get a driving rainstorm.

I'm already happy with the snowfall I've received, any more is bonus.

That doesn't mean that at all. If you have a strong high/weak low you can get a good overrunning situation like Feb '03, a long duration heavy snowfall for a large area.

I know it is possible but like you said the GFS suddenly pops a storm after not having one and decides to give NYC after having single digits-teens for lows just hours prior a Flood of rain. To me that is beyond ludicrous. Hey anything is possible though. That said, I will stick with the EURO for the time being in this time range.
