The euro really doesn't add anything to the discussion. It's just a possible outcome at long leads. The entire pattern/premise remains intact so far today. 


Looks like the euro is faster with the storm too - looks like a january 6th deal this run.

The run was well within the ensemble spread. We're surviving another suite so far. I expect the ens to up the ante again. They "generally" follow the ops lead inside of 9 days.

There's a huge range of outcomes on the GEFS. Euro has quite a different solution vs the 0z run. Lots of possibilities on the table, but the pattern is favorable for snow for us starting around the 5th.

Oh damn..that is a pretty nice setup.  Bump that high up to 1040, moving it just a bit south..

Compare the NAO and 50:50 low on the euro and GEFS. Euro never pushes the NAO ridge far west, which allows this storm to come farther north. Given the seasonal trend, I think that's  more likely than seeing some suppressed storm that snows on Atlanta.

Unless the wave speeds way up, a west track is still totally fine for us as long as we get hp over the top. That has been pretty consistent regardless of timing so far. 

the qpf max is narrow pretty much on all guidance. That's probably the biggest worry. Not getting any precip vs getting all rain.

Seems we lost the thumbnail ridge poking West as DT spoke about last night, on his site's update.  

It was on the Euro run yesterday

Unforgivable

Probably one of about 3 things that could drag me into actual fight at my age.

I think some of our people need to listen to the voices of experience here.  This is way, way too far out to even think about what an op shows.  The takeaway is that the pattern looks decent and all of the models are seeing a storm.  That all are seeing it is a big deal.  With the recent trends, I'd say suppression can be taken off the immediate worry list.

Looking at h5 and comparing today's 12z run to the 0z on the euro, much more of a SE ridge on 12z run. Explains the more NW track, and supports the range of solutions still on the table this far out.

It's the depth of the trough in the west that's causing it.

There are some small differences in the AK ridge, the western trough, and the ridging near GL(not as far west) that seem to contribute to it. These are the kinds of variations that we are going to see with the op runs that will drive certain people crazy for a few days.

I agree and I suppose one could argue that the stronger ridge in the se is causing the deeper trough in the west.  Given the past 6 weeks, I'd lean toward the stronger ridge.

I would also lean towards the NA ridge/50-50 low not being as strong or in the best location. Interested to see the EPS and then the 0z op run tonight. Both the 12z and 0z op runs yesterday had an almost ideal h5 look for our area given the overall pattern. 12z today shifted things just a bit, which is fine as long as it doesn't continue to trend in that direction.

Still a lot of spread but the euro ens "generally" support a more northern hit like the op. The control run is a destruction. It's a 2 wave deal with the first hitting central/southern VA and then us. 

Scanning through member output leaves little confidence in any one outcome and the shift overall wasn't very significant.
