It doesn't look better at H5.. there is a strong lobe of PV holding just east of Maine at 84 hours knocking down heights in the east and creating fast flow out to sea while the system is trying to phase

It's definitely worse than 18z but it certainly isn't the worst setup I've seen! It is an OK looking setup... really close to getting a nice phase if that PV moves west of weakens quite a bit.

Like I said about the EURO locking into a soloution like a pitbull int his range.....we saw it even a bit earlier with that cutter.... I knew it was over at the gtg.....folks kept telling me I was nuts.

I think it's over, but I'll wait for the EURO to hold the course, which it will.

Not even a dusting here on the Euro (or 00z GFS for that matter). When was the last time Nashua, NH was in serious jeopardy of not seeing a dusting of snow before Christmas? This is unreal.

Hopefully we have a D4 12z miracle.

Pretty sure the problem was what I said.. it hold the PV steady east of Maine for too long... the 18z rotated it back to the west for a partial PV phase.. the 12z shredded weakened the PV enough for it to amplify anyways. We got neither this run.

It misses by so little....I was sure it would do it up and so did most mets on the bb. The GFS went in one direction but then held. We need the Euro to help us. GFS 50 miles west is a huge hit for most.

I know I said I'd wait until 12z Thursday before giving up or becoming concerned but I'm going to retract that statement if the 0z euro is a similar solution to the GFS.

Yeah actually I sort of like this.. I would rather the PV trend east and weak and get the southern stream to amplify up the coast, VS a PV phase which could flip me to rain

This is still really close.. a slightly stronger southern s/w or weaker/more east PV would let it amplify enough to effect the coast, like the 12z gfs

This is a step away from the 12z euro though I think, while the 18z was a step towards it

we need the PV to weaken and move east or to retrograde west and let this thing turn up the coast. We get the in between screw job this run

Here's what I saw...the southern stream shortwave looks stronger at 0z with a finger of vorticity from the PV reaching down to try to amplify the system on the 0z...18z looked like less vorticity with the shortwave and not as much action from the PV initially, although it changed later in the run.

I thought your worries of flipping to rain lasted too long. The longer wave pattern would have to have a mega phase to change you over....if we assume the Euro was being correct with the larger scale features.

I've been more worried about a whiff east vs a cutter west for about 36h now. I do still think there is plenty of room to get a nice hit though....the Euro is quite close despite some people hanging themselves already at over 100 hours out.

Longitude might be your friend in this.

The PV "reaching down" is not trying to amplify or phase with it.. it's shredding it apart.. a PV phase would have the vorticity rotating in from behind not sitting NNE of where we want the storm to go and knocking down heights along the coast.

Hopefully mine too. 12/26/04.

Yeah for the last 2 days it seems like the big threat here was a whiff rather than a cutter which was going to take a lot of work to do. It seems that fear is coming to fruition but the pattern is still quite unstable and close to something substantial still.
