Well yes but its the location of the MJO that blows either way, region 5 just might be the worst octant in existence for us in December. If I remember correctly it was the euro that had the MJO stalling out while the GFS had the wave surging through the octants until the GFS jumped in with Euro. Regardless of the speed the MJO it looks iffy at best for us likely through Xmas, at least that's the way I see it and I've been wrong plenty of times before.

We can score without a perfect setup (or so ive been told :P ) but I don't feel comfortable relying on a +PNA during a Nina.

For what it's worth, the 00Z had an interesting look when looking over the ensemble members. For around the 5 day time period the members were pretty uniform in a decent alignment and placement of the PV for the East Coast. Most had heights building into Greenland with about half of the members showing, at best, signs of a transitory pseudo 50/50 low. One of the key differences though was basically the timing and placement of shortwaves dropping around the base of the PV with most members showing some sort of event in the 4 to 6 day period. 3 members, with decent timing of these features, actually had a decent to a fairly significant snow event for the Mid Atlantic.

Not a big fan of the off runs but interestingly enough the 06z GFS op has these features showing up as well. A 50/50, Heights building into Greenland, decent PV placement with decent timing on a shortwave. Not surprisingly it also shows a significant snow event for the Mid Atlantic.

Most of the 6z ensemble members have the storm, one way or another. About 5 of the members look like they'd be accumulating snow for our area. A couple look like snow-to-rain, a few just rain and the rest either don't have the storm or keep it out of our area. I'd call that fair consensus.

To be honest. While I am pretty confident of an event in the East around the 5 day time frame I think what we see with verification is a storm riding up to our west where the mountains and inland areas to our north do well with snow. One of the key factors will be the PV placement and alignment. What we see often times is the models have a habit of overplaying the southern and eastern extension and I think that is coming into play now. Earlier runs have had this suppressed and out to sea and have progressively moved it left and north as it draws nearer. The 00z members had a decent PV placement and it looks as if the 06Z followed suit on that. But if you look at the individual 06Z members they seem to have pulled the PV a little north and west of the 00z and you have to wonder if the 12Z suite will follow.

The SNE crew is all convinced this storm will be completely surpressed south, while the MA crew will all be watching the inevitable northward trend all week. Congrats NYC?

At five days there is plenty of time for changes but to me with the progressive shift west and north over the last few days I would think that would bode well for those farther west and north at seeing snow. I did see mention that the #1 CIPS analog from the 00Z showed a nice hit for the Mid Atlantic so there is always hope down here.

I guess this is more like summer banter, but don't know where else to put this. I'm at a conference and I overheard someone yesterday discussing climate projections for the Mid-Atlantic. He said, in the "business as usual" scenario from IPCC, the climate model he used showed an Arlington to north NJ corridor having normal high temps at 100F from the beginning of June until end of August. He used a 10km resolution model. Congrats Ian?

too bad most of these guys are full of it with these predictions....
