FWIW the 00Z RRFS at 84 looks like the GFS down in GA as far as having precip being much more west. Its been largely awful though this winter season though its done okay on some systems.

The differences down in AL/GA/SC with the GFS vs like everything else is laughable lol....don't worry guys, 1 inch only shuts those places down

Seemed to work til 2014-2015. Since then much less so. I think after the Euro upgrade in that period the rule kind of went out the window.

UK is just wacky at times. I would not be concerned at this range. I have as matter of fact said the past decade whatever the UK does the Euro does the opposite. I have not kept tabs closely but feels since about 2015 when one makes a notable move at 12 or 00Z the other seems to do the reverse. UK has given many of us along the EC hope only for the Euro to say no. The old rule of them moving in tandem holds less frequently these days

Was gonna joke the UKIE would get cold feet and move the other way. Seems to always begin waffling once inside like 108. I have also said before the last 10 years whatever the UKIE does the Euro does the reverse so watch the Euro have it raining on the Cape now.

Its early but not sure I see a scenario as LIKELY at the moment where RDU is in trouble with this as far as ptype. I'd still be more worried about a miss than being too far W.

To be fair the EPS has actually been pretty close to the GFS idea last 2 runs down in SC/GA. So its been on the train the most in prior model cycles of this at least being far enough west and organized down that way to be a factor up in SNE

Its rare to see the GFS actually be the one showing this when nothing else is, albeit everything did move in that general direction and the EPS has been more west too. I think this for the moment is still an outlier though. We need to see this organize pretty far west down in SC/GA in order to get something to be a hit for most of our area.

The main reason that event has sort of tamed is the SER is not quite as strong as it was being shown to be in that period next week anymore. I still don't love Sunday due to lack of a high in SE Canada, it would need to be a pretty close to perfect setup right now

It IS a sloppy phase but also there's no real high in place in SE Canada so probably even in a clean setup that one verbatim is close.

It looks pretty transient to me. I do think there is a window there 1/20-1/23 or so where a storm likely happens but right after that we continue to see the 3 ensembles all more or less go back to a +PNA look again or a hybrid -EPO/+PNA look that may be briefly suppressive. I think 1/24-1/29 may favor the MA/SE. After that might be a 2 week window up this way. I am now becoming more confident we carry this ti 2/10-2/15.

I would watch MS-AL-GA-SC Sat-Mon. Something may come out of nowhere inside 4 days. UK has been showing it on and off and does again today. Remember that the GFS/Euro sort of suck with killing shortwaves in these patterns. The ICON does not really show much now but unfortunately 2 of our main models have issues with Gulf Coast slider type events which is why so many of those historically have popped up inside 96 hours.

At the moment it seems next Wed-Sat is a window to watch. I'd favor the interior or Lakes right now but we've seen the SER be overdone at times. I think after that for awhile we may go a bit suppressive and the pattern from the 24-29 may favor the SE or MA. It could be when we begin to see a relaxation the week following that we could see a coastal event.

There will be a 2-3 day period next week Tue-Thu or Wed-Fri where the SER builds briefly. This is probably when the OH Valley/NE likely sees a big winter event but thereafter the +PNA likely comes back and that may be a broader trof which makes it more likely a winter event hits the SE somewhere in the 23-30 period

I think it still eventually goes but I had said a week ago the +PNA was likely going to hold longer than ensembles showed. They've just been bad past about D8-10 this winter but reasonably good with the pattern ideas up til D10. I think the EPS at D16 may be showing signs of a breakdown coming soon after that. The evolution back to the -PNA may not be the typical shift west of the EPO/PNA ridge but may be the Pac jet smashing it down and then the -PNA evolving after that. If you loop the EPS from D14-16 it appear maybe if ran out to D20 that would be what happens.

I am just amazed how good the long range ensembles have been this winter with the theme or setup of the pattern inside about 192 and how bad they have been beyond that. Now we have the ensembles today briefly trying to go -PNA but then seeming to be shifting everything back towards +PNA again by D15-16. I think most likely the overall idea is the +PNA is going to hold longer than expected as that regime once it establishes as hard as it is going to here it is difficult to boot it out. I have no real ideas beyond that because the MJO strength is a big issue if its strong or weaker

Beyond D7-8 but inside of that they've tended to get the pattern theme close. I'd feel pretty good now in the SE in that window from the 14th-20th. It may carry past that because I believe the +PNA will hold longer than currently modeled. We will eventually go to a -PNA/-EPO with a SER but that might not be til like the 27th or 28th despite what ensembles try to show.

Chances are even if those MJO forecasts are correct it'll be the 27th or later til any impact on the pattern happens but it would argue February is mild in the east if a strong wave is going through 5 or 6

The ridge is still probably too far west on the GEFS though. I don't think that is what happens but if it did that is not a KU or coastal setup really, its again very 93/94 like but I think if you're Philly north you take that

Given it caved to the GEFS look from 2 days ago when the GEFS basically caved to the EPS I think we can toss it somewhat. I'd also be wary of how all 3 suites go from this booming PNA to a -PNA in the blink of an eye in the D9-16 range, we all know pattern changes tend to be rushed so my feeling is we end up holding that pattern from 240-320 or so for awhile vs hard flipping right to a -PNA/-EPO with a SER....that idea MAY be right but would not surprise me if its like 1/27-1/31 before that happens and then by 2/10 we are in a classic Nina Feb look and we're done unless we get the Nino March transition 2nd winter peak

It was always likely the GEFS was gonna be wrong, its been having PAC issues now the last 2 winters. The one area I feel its been better is the NAO. The GEPS caving to the GEFS yesterday was funny though

fortunately with a high end weak to moderate El Nino likely next winter we should finally get out of it

Hannibal has 33 inches already, its only about 5 south of Oswego on a straight line

February I still feel is a lost cause, although if we delay this flip it makes it more likely February, at least maybe the first 10 days is serviceable. There has been 1 guy consistently hyping February though since like October and thats Larry Cosgrove who has been saying 1/20-2/15 is pretty much the window for this winter and has not moved off that idea.

That said I think only NYC/LGA had above normal snow and that was by like a half inch maybe, JFK was shutout or close to it. This Dec was overall a snowier pattern, it would be quite the surprise if January ended up even like +3
