    If the cold arrives this weekend, the GFS is already in “bust mode” as it, at one point, had several runs over the forum area never went below normal and was under a standing wave. The model is likely behind right now, and won’t catch up until the pattern changes. But I still cast a wary eye. Thus question is worth asking so that we ourselves don’t follow bad modeling off a cliff.....What exactly is the GFS handling poorly? Is it a bias? Is it right on some level when biases are accounted for? Or is it off-the-wall bad right now? One set of models is in for a fairly significant bust.

    Been super busy for the past couple of days. If you haven't looked at today's ensembles, you should. No idea if right...but. The ensembles are close to the coldest that I have seen them in the d10-15. Pretty rare to see ten degrees below the average at that range on the EPS. The actual EPS at 12z was throwing at a big dog pattern. Looks like the first cold front is still moving forward in time around the 16th.

    Afternoon ensembles were pretty much a beaut, Clark.

    If I lived in northwest TN right now...I would be chomping at the bit. The pattern is loaded for bear from a line from Memphis to Nashville and northwest. I hope NE TN can get in on the action (not holding my breath). A classic Nina cold weather outbreak is set for the western half of the state IMHO. I am really interested to see if that line can press further SE.

    Nina winters are huge for the northern Rockies in terms of snowfall. Water content in the snow can lack at times as it did last winter - lots of cold, fluffy snow and water content was low.

    Well, I see the operationals have all "found" the block now. Suppression city. Now, I think we start to see systems attack the base of the block where we are. Very good adjustments today.

    I relearn this lesson every winter. Models often go haywire right before and just as cold air shows up in the medium and long range in modeling. Guessing this is a Montana special(cold) that bleeds in an ever modified form...eastward. Winter chances increase as one goes westward(from the Apps) in this set-up.

    The 0z Euro control is insanely cold over the Plains and Front Range. That is a fantastic set-up for those who live in western areas of the forum. The EPS supports that look(core of the cold in the western Plains) w/ the furtherest extent of the cold reaching the Atlantic. Remember the strat split a while back? Yep, that is where it normally dumps cold first in NA(if it goes to NA), and right on time 2-3 weeks after the event. Would be interesting if the background driver was a combination of SSW and Pac forcing(not the good kind). Anyway, the set-up depicted is very similar to the over-running event for Memphis a few years back.

    Maybe the GFS is offering up an apology after an absolute cluster of a week. LOL.

    The cold bias of the CFSv2 (as noted above) is almost always apparent. The 18z run today was especially good. The model does have some useful aspects at 500. Beginning of the run -> next ice age.

    I can’t say that I like a 7-10 delay in a modeled wx pattern. One winter recently we waited all of Jan/Feb...for what turned out to be a cold front. The upcoming pattern change at mid latitudes is now set for the 16th. At one point it was the 11th. That said, there is decent model agreement this afternoon which is good. Is that consensus or just one common point on a grid as two ships pass in the night going opposite directions? We will know soon. I am optimistic but also a bit more cautious as the colder pattern has been sort of stuck around d10.

    We are going to see a fairly epic model fail by either the GFS/GEFS or the CMC/GEPS/Euro/EPS in the medium and long range.

    Captain didn't get back on the first goal, and his man scored as a result. Pretty much each USA goal was simply due to not marking their men. Plenty of chances for the US. Moment wasn't too big, but we need a finisher. Memphis......not just a city in TN.

    Euro Weeklies, if they are right, show Dec15-Jan5 as our best chance for winter. Is Cosgrove controlling the Euro Weeklies? -NAO retrogrades(?) to an EPO/PNA ridge. Eventually, the trough moves out West and doesn't budge. Looks like '89 without the cold temps from '89. It does have Christmas as cold. Nice pattern IF it will verify. One thing I hold onto is that -NAO patterns tend to resurface later in winter.
  15. Carvers Gap
    I don't think we will torch(till later in the winter). But it is definitely having trouble w/ the block IMHO. The Euro has this inside of d10 now, and it looks remarkably like what ensembles have had for a couple of weeks.
  16. Carvers Gap
    The 12z Euro is what I think is a realistic pattern evolution for the next ten days given the block in place and potential for the Pacific to start lending a hand per John's post above. It is supported by the CMC and GEPS. For now....I am tossing all runs of the GFS (unless it verifies....LOL...but which run do we pick?).
  17. Carvers Gap
    I think a Euro/CMC blend is probably in order. The GFS is all over the place. I give it some credit as it was first to find that the pattern was not going to be favorable prior after the 15th, but man...I don't know if I have ever seen it this erratic. The Pacific is just not cooperating as well. The other explanation is that very cold air is about to enter the pattern in the d10-15. That could explain some things.
  18. Carvers Gap
    I saw that. I think that is good advice. I also think you are right that modeling was a bit too quick...
  19. Carvers Gap
    I am beginning to wonder if the GFS operational is even usable right now. It is either going to score a coup within its own suite(GEFS doesn't agree with it nor does any other global or ensemble that I can find), or it is an outlier which isn't really consistent. I may move forward with a Euro/EPS/CMC/GEPS blend. Has the GFS been updated already?
  20. Carvers Gap
    One storm....just for kicks and giggles.
  21. Carvers Gap
    Yes, yes it was!!!!!
  22. Carvers Gap
    Just for sharing and no comment on my part. Will these looks hold? I want to see a day or two more of consistency before getting too carried away on my part. The highlights of the 12z suite of global models... @*Flash* An old saying on AmWx(and its predecessor), when we are talking about the MJO the patten is usually not good. True point on your part.
  23. Carvers Gap
    The 12z Euro follows the CMC lead w/ potential for a wave riding the cold front in the day 9-10 range. Take w/ a huge grain, but the GFS sort of had it as well. With the potential for so much cold to be moving into the east, it makes sense for a wave to ride one or more of those cold fronts.
  24. Carvers Gap
    This is the third straight set of runs where winter weather and very cold temps are showing up on modeling.
  25. Carvers Gap
    The Canadian has snow falling w/ temps in the single digits on the Plateau.
