Euro has the shortwave at 150...a bit stronger with the confluence than the GFS but the surface low is in a similar spot and the precipitation field looks good so far. Let's see if it can trend better here.

All of the guidance now has the potential..so I think it's safe to say we have something to watch here.

That's what I was thinking.. all the models have the shortwave. From there, we will have to see where it goes.

Northern stream trying to get involved at 156...this may end up a bit worse than the GFS though given the confluence over the east. Still good to see it has the system.

Why would this be worse if it phased more? Could it drive a cutter west of us despite the confluence, or just suppressed? Wouldn't phasing eliminate the threat of suppression?

Good lord you must be young. It is played every year (since 1968) and is the most well known Christmas special along with Charlie Brown.

Im going to buy it though-- if we get snow on Christmas Day, it'll definitely put me in that mood.

Sounds like that -4SD NAO signal doing its dirty work.

I don't think there's much room for this to cut inland given the height field and orientation..but that could all change so who knows right now.

186 the Pv is phasing in big time now with a lobe coming in over the Lakes...snowstorm DC-PHL-NYC (lighter in NYC)...1008mb surface low off the coast southeast of OC, MD.

Cue the sleepless nights and days for snowlovers.

Here is something that we could do with every threat. We could put a pinned thread and outline what could cause the storm to miss, ie synoptic features that might change. It would probably provide for less posts about what is happening, and consolidate and streamline the entire posting process.
