EPS went all 18z gefs on us. lol. Ji does not approve

 

DT will be retracting his aleet shortly. 

meh...its not the worst look. Seems like the SW trough is really overdone. wouldnt take much for it to be a much better look ecmwf-ens_z500a_namer_11.png

IDK Ji. It was a pretty terrible run. The last 3 runs progress forward from the d10 sw trough. 12z run doesn't do that at all. It's just one run but it looks pretty much the same as the 18z gefs last night. That's 2 ensemble runs in 24 hours showing a pretty stout SE ridge. Good thing we have 10 days to hope it goes away for good.

well its the GEFS/GEPS vs the EPS.....that sounds more assuring than the GGEM/GFS vs EURO. We can always use the euro likes to hold things in the SW weenie rule

My guess is the return to cold is coming one way or another before the end of the month. The differences on the ens is timing differences and not whether or not the return to cold exists so that's good. Would be nice to not have a warm holiday though but we can't do S about it one way or the other. 

The good thing is the pattern transition is looking to be pretty wet in the SE/MA. Would prefer to see that versus a cold arctic front followed by dews in the single digits.

yep....would be crushed if we wait all this time to get into a wet pattern and its all rain.  I looked at Raleighwx charts for MJO and for DJF, phase 1 us usually a eastern trough...guess that is also something to watch. http://www.cpc.ncep.noaa.gov/products/precip/CWlink/MJO/CLIVAR/ecmf.shtml

If I were to guess, the EPS might be a bit behind of the GEFS. The GEFS was the first model to latch on to the potential of SE ridge during Christmas, and then the EPS followed that idea a day later. The EPS might be playing a bit of catch-up. Still a big improvement from 24 hours ago. This room turned into the panic room... lol

This. If it were not for people trying to will a Christmas storm in here, the large takeaway would be that at some point from there to early January, the cold will return, along with moisture.

Op way out of range or not, I really like seeing what the gfs is showing @ h5 by d8. The ridge axis centered on the west coast with even just a little help from the NAO can allow things to amplify AND keep us on the cold side. At least we were spared staring @ a SE ridge/SW trough this run.
