Now stays, ok...but it's going to come east especially if we get a -AO or -NAO later. Jesus even he's jumping, I didn't think it would get this bad once the Euro got in range but I guess I was wrong

 

 

The D10 Euro, even if it verified perfectly, doesn't look like a stable pattern, which is what you were pointing out.  I just wanted to reiterate that.  We may have some fluctuations on the way down.  The Euro could also be exercising it's bias of holding energy back in the SW.  I don't know.  But I do think everyone will feel better when the Euro finally starts consistently showing ridging west/troughing east well inside of D10.  If we're still fluctuating after the first week of January (if we don't have good clarity around a near-term cool-down), then I think questioning the outcome of the month of January will be legitimate, at that point.

 

 

DT must be hugging the EPS because the GEFS looks great to me unless I am missing.  Although, I just read the twitter exchange, sounds like he is hugging Al's GWO analogs which predicts a cold central US.  With that analog we would Apps runner after Apps runner.  Will see...

I agree the GFS is fine which is when in my earlier post when I compared OP Euro/ Euro ENS of the 00z I said forget the GFS for now. It was the gripe over the 00z Euro that I think made people doubt the cold, forgetting we have other guidence and OPs can flip flop during this time.

This is a nice setup. Trough east of HI, too.

yes sir!!

Thats a LOADED weather map.  I would take that for a million bux  ok, not really...but the map looks really good.  The Christmas storm looks like its gonna go BOOM!, but the energy is further east so it doesn't dig as far.  I am ok with that.  The maps still look pretty good to me in the long range, especially on the ENS.  I love that look.  That is trouble waiting.....

I think I'm gonna be wrong. In years with a stronger southern jet the gfs does terrible while the euro excels. So far the gfs and it's ensembles have been doing better than the euro.

#Surprised!

 

True, for storms inside day 5-7, but JB had the NH stats out the other day showing the GEFS has been really good as of late.

I may be rowing that boat with you. 10/10 times I'll go with the Euro in a split flow.

 

Something's just fishy.

Just curious, how did the Christmas storm look on the Euro? I know previous runs had it bombing out in the Great Lakes. Could there be a Christmas Eve severe threat for us?

 

I'm not a severe expert by any means and I don't have access to a lot of the severe parameters, but the western half of NC tops out in the upper 40s while the eastern half is in the 50s.  850s are +4C I-85/west and +10ish in E NC.  Then again, we suck at severe weather out in these parts, so no surprise.  There's a 993 mb LP just north of PGV on Christmas eve morning.  The timing doesn't look especially good for thunderstorms, either, with it mostly occurring overnight.

 

Christmas Eve looks like highs in the upper 40s in the west and low 50s in the east with lows Christmas morning in the mid 30s in the west and near 40 in the east.

Thanks! I know earlier it was showing a pretty sinister apps runner that bottomed out around 960 in the Great Lakes, and that sort of set up could lead to severe. If there's a lp around Pgv, that in itself probably means no severe.

There's actually three different LP centers at hr 144.  There's a 991 mb LP over northern Lake Michigan.  There's also a 998 mb LP over western New York.  Finally, there's the aforementioned LP north of PGV.  It rides up the cold front and completely bombs out on Christmas Day over Quebec.  It gets as low as 965 mb on Christmas morning, but by then the cold front is well off the coast, so it won't have any effects on us aside from drawing in gusty winds and cold.  I would expect it to be a pretty killer setup for NWFS in the mountains.
