Seems like this run of the gfs is a blend of previous gfs runs and the euro....still room to come West???? Maybe

I just did side by side h5's @ hr 45 & 51 and compared with hr 51/57 with 6z. It's a huge step. I think I'm caving on this one. I've tried to fight the urge because it's so damn time consuming picking apart every run but the GFS just pushed me over the edge.

The upper levels look prime for our area.

Look out for a deform as it becomes vertically stacked.

Could be ultimate occluded screw job for SNE.

LOL and then we you are up here, you'll be saying that about the MA.

This will be a strong storm everywhere. Certainly DC burbs into ERN PA are under the gun for a 6-10hr pasting.

Always nice to see you pop in and say things like this.

What time frame are you thinking for the 6-10hr period?

Thanks for these side-by-sides, Bob. Very helpful. I hate clicking back and forth between browser windows/tabs. I agree it's a fairly big step. I admit to not paying very close attention to this storm yet (November snowfall suspicion bias), but hasn't the GFS been bouncing around a bit for the last few days between OTS and something close enough for precip in our area? Either way, a change at this stage in the game, ~72 hours out when the vort is being well-sampled, should be given more weight then one 3 days ago.

No prob. I'm really efficient at it and it really helps seeing them right next to each other instead of trying to toggle. I'm going to add 0z to the side by side and post shortly.

The nam is doing the same thing so I don't think this move is just a "bounce". It could be but thinking about how steadfast the euro has been and now other important guidance has made a clear shift combined with how short of a lead we're at really brings some optimism. At least for me it does but I'm always biased and since I'm a weenie it doesn't matter what I think. lol.

Valid to be concerned about the Euro overamping. It's done so at least a handful of times in recent winters. However all the globals have a big storm for the most part. GFS is so often east in this range it's hard to say its any more right than the Euro. IMO you should weight the Euro/ens at the point where we currently sit.

I only have free access to the Euro's ensemble members, so while I can see that the OP and mean are in agreement I can't see what they look like between 12Z and 0Z on Wednesday when the mean ends up further a good bit further east and weaker than the OP. In fact, the 0Z Euro mean looks pretty similar to the 6Z GFS mean at 0Z Thursday:

The GFS members show a decent amount of spread, though. So much so that eight of the members are basically duds for us, two are great/decent...and two are Eh...

I wonder if the EC members are similarly spread thus resulting borderline okay mean solution that doesn't actually represent the opinions of any of the individual members?
