  1. At this range I seriously only trust the RGEM/Euro on a system like this...obviously the GFS is gonna over torch the BL among other problems the NAM/ICON/UKMET just cannot be trusted for various reasons...by this time tomorrow we can probably begin to trust the NAM somewhat
  2. Never ever trust the NAM past 48, especially in involved setups such as this. In general the NAM is to be trusted when it shows virtually no run to run changes...see January 2016 or February 2010 when that thing did not budge one inch on its idea from 84 hours in. Any time its moving all over its useless
  3. It always helps now. This is why storms of 12 plus since 2000-2002 have become commonplace. Crazy pwat values and just bombing storms which I blame fully on warmer Atlantic SSTs. This is why I still think something big can happen for the metro here. If there is potential for faster phase/intensity these days it tends to find a way to happen
  4. NYC has only 2 events where they record 1 inch of rain and then 5 inches or more of snow...12/25/02 is one. I cannot recall what the other is but Bastardi has posted it a few times, he uses it as an example that in general if you get significant rain the system better be undergoing a massive bombing or phase or it probably means significant snow after the changeover will be near impossible
  5. Much like down here in NYC we usually get 1 week of good weather in mid January in raging Ninas or really ANY Ninas with bad patterns like 96-97 98-99 Seattle has a track record of cashing in during bad Nino winters for them too in early to mid January before the background state inevitably goes to crap for them again
  6. Numerical numbers show DPs around 32...its really close...as currently shown I think NYC is 34/32 in there and maybe it accumulates verbatim if its coming down crazy hard but current thermals to me fall short unless this thing can further phase/bomb earlier...no doubt the fact it will be overnight would help, even in January
  7. The Op Euro being the most east at 96-120 is scary...obviously Op runs should not really be used heavily at this range but its something we've rarely seen since its most recent upgrade on stronger systems. I still am telling people today I more fear a total or near total miss down here than I do this tracking overhead
  8. Obviously you never should focus too much on Op runs at 100-120 hours but I cannot remember a single major system where the Op Euro was not overamped the last few winters...the fact its consistently been the most SE the last few runs is sort of concerning to me as that has rarely happened in recent years on stronger systems at this range. Its a very apparent bias that is absent the last 2 days here
  9. I am still slightly more worried about a miss than I am this coming too far NW. I think its highly likely all the snow droughts at the stations end though they may end with only like 1 inch if we end up with the more west track close to us
  10. If we assume EPS too weak GEFS too strong but also too slow as its been recently we probably can blend the ensembles and it'l be less ridgy in the east. I guess its a question does the wave die before it really gets to 6. Ideally we probably want it to because if we have to survive even a weak push through 5-6 that takes us to 1/20 probably. I think there is a better chance of a +PNA late month if the wave dies in 5 or early in 6
  11. It was discussed a ton in the MA forum the last year why it seems we now get an SER in patterns we never used to get it in before. Nobody really knows why
  12. It just reeks of a setup that works with shorter wavelengths. I'd think its highly likely in early January its a miss but might work in late March
  13. You'd need to avoid the overphase or early phase but its not too terrible
  14. I would not even describe those as Nina...those long range ensembles would be torches everywhere...they are both 01-02/11-12 like minus the brief periods in those winters where we saw SERs...there's a ridge in W Canada and trof in the east as far as mean heights but there would be no cold aie.
  15. Maybe but ensembles do not often really respond to MJO forecasts at D12-16 very much...its possible more than anything the GEFS for whatever reason was trying to revert to a Pac base state that in a Nino is just not likely to happen and as we move closer in the look changes. I was warning people 3 days ago to be wary of any strong push through 4-5 in an El Nino that might be showing signs of coupling more based on SOI in recent days...just like forecasts of a strong 8-1-2 wave last winter were not realistic
  16. Its been too amped in a short sample size so far the last 6-8 weeks...it almost always does better than the EPS but it was way too amped on the wave forecast in mid december
  17. If you scroll through the 12Z GEPS/GEFS it seems already at 360-380 its reshuffling out west and the low is retrograding back towards the Aleutians with slight building in heights over W Canada and the block in E Canada lifting north...its like if you can just run it to 480 hours we'd be right back to an eastern trof.
  18. DT has torn into those calculations for years...he's shown how the -NAO stats can be wrong at times where you might technically have higher Greenland heights and lower Azore heights but its not really a -NAO, or certainly not one which impacts us in any positive manner for snow or cold
  19. I am still suspect of any long duration -PNA pattern happening...depends largely on what the dynamics behind the change are but if its strictly based on the MJO going 4-5 I am far from sold it happens.
