The RGEM only goes out to hour 54...what hour 60 are you talking about?

Yeah, they are not the same model. I'll correct myself by saying Hr 48 compared to the GGEM is SE. Thanks

EDIT : I also didnt see the 18z RGEM so I cant compare...

I'd agree with the statement that it looks like an amped version of NAM.

Over in the NYC forum, Earthlight and some others are saying it's more amped (at least compared to the NAM). Scratching my head here...

it is more amped then nam a little and gfs for sure but if you compare the rgem to the euro at the same time it is well east and weaker. Euro is back over south central ga with slp while regenerate is off the coast already. Next frame euro has slp inland over sc and rgem is already east of there. But doesn't mean it won't pull in later.

People are honestly getting ridiculous with these maps and terms. A power company blamed the polar vortex for increased wattage rates 

 

I really can't believe the very high numbers getting thrown out by some at this point. It's going to take a humongous bust to tone down some of these forecasters. While I do personally think this will end up on the western end of guidance eventually and likely a significant snowstorm for some portion of the Mid-Atlantic/NE,  I've not seen enough personally to more than acknowledge a region where 6"+ is possible. Certainly not going to throw out 12-20"+ like we're giving it away on the Oprah Show... and I'm for damn sure not calling it a possible blizzard right now.  

While it's still early in the game for using the SREF plumes/probs, I don't really see alot of support yet. While there are a few big members, 21z SREF mean QPF in Harrisburg, for example is about 0.3".The tight precip shield being portrayed is a concern, especially for me, Jamie, and the rest of the UNV gang back this way. The I-81 corridor below I-80 should be okay for at least a light-moderate snowfall. I think it will ultimately be a bit more expansive, and get into C-PA more given the generally favorable low positioning. How much so is still up for debate. It also seems to me that this storm maxes out with its high end potential rather early, mainly for the Mid-Atlantic region more so than the northeast. We shall see how things play out tonight and tomorrow.

Running the low inside over eastern NC to it's eventual position just off the Jersey Coast is why it gets precip way deeper into PA. This is about how the Euro has been wrt this part of the storm tracking from the Southeast. Having the low developing off the SC/NC coasts and turning up from there ala the GFS/NAM isn't going to to cut it for most of us in here without downstream blocking to completely close the storm off.
