  1. A shortwave basically ran underneath a massive arctic high and dropped 5-7 inches between 10pm-6am. http://www.meteo.psu.edu/ewall/NARR/1994/us0126.php
  2. Given how key the NRN stream is I like the GEFS for this as far as how does storm evolve...now as far as what does the WATL/SE Canada area look at as far as blocking? I'd probably blend the GEPS/EPS idea and see how it compares to the GEFS. I feel the GEFS gets outperformed on that so the eventual track of this thing whether it goes OTS or tries turning the corner/speed of the system may be better to see what those models are indicating in that sector
  3. GEFS/GEPS/EPS still showing warmup does not last long.....still don't totally love pattern on any of them for big snows though I think GEFS pattern has improved a tad since yesterday...general issue is +NAO so W ridge has to be perfect, if its too far west you cut, if its too far east you might see everything miss OTS....the GEPS from 360-384 looked best, maybe was trying to build a -NAO late and the PV was dropping S
  4. My guess though is by time it got in it would not matter much. I think in a setup like this 90% of the snow or precip would happen prior to the switch, thats the advantage as we know to not having bombed overrunning/WAA events like we see so often now...we just do not get those 2/8/94 or 1/26/94 type events ever anymore...everything is an amped shortwave or deep low
  5. The HRRR can suck for thermals sometimes but as far as precip/track depictions at 48 it can often blow away the NAM on occasion.
  6. Add the UKMET to what you want if you just want a light event...pushes core of overrunning right over most of area...coastal misses but as I said you probably sort of want it to in this setup
  7. January 92 I was in ATL they got 5 inches (totally unforecast BTW) it was a similar narrow stripe to that....funny thing is at the time NYC had yet to register 1 inch that winter and entered March at 2.5 I think til two storms happened in 5 days bringing 10-11 inches. That was also an El Nino winter with some similarities indices wise to this one
  8. The problem the metro has is the main initial round now looks to go mainly NW and the coastal probably is too far east...there will be a screw zone between, there has been a slight SE move though on the some models the last 1-2 cycles so as someone said above, a mix of the GFS/RGEM is really the best for the metro itself
  9. The 1/2017 storm was odd in that a LP which originated off FL managed to come N enough to impact us, nobody had ever seen that before, if we see the same happen again and get a substantial snow event out of it it just adds to the list of odd things we see that we never used to
  10. Band will be south of stadium by 1-2pm I think, they just did not want people driving in it. I feel maybe having it at night would have been fine
  11. It never makes big run to run changes inside Day 4 really but it can incrementally go NW or SE repeatedly for like 6 cycles and next thing you know its moved 100 miles. Sort of did that to us last storm down here in the 2-3 day range
  12. System is heavily NRN stream involved...GFS/CMC might school the Euro on this one til we get inside 90-100. Vice versa looks like it may happen on Tuesday, tons of SRN stream activity and GFS now looks to be the most lost of any model with that one
  13. Inside 90 the Euro never makes large moves but it can just incrementally keep moving one direction...to me the most glaring thing is the RGEM/NAM agreeing somewhat past 60...that is not something we see too often, when you see that you have to be concerned the higher res models might be onto something.
  14. Models went through a bit of a pullback yesterday delaying the reset but overnight ensembles sort of went back to things looking fairly good again by 1/27-1/28 after 1/21-1/26 are fairly warm...the problem is the pattern is largely just a cold dry/warm wet look outside of New England...the NAO is positive and the western ridge is too far west on the GEFS/GEPS...the EPS is better but the pattern still sort of screams that any big storm would cut N of the MA or SE US. Regardless, there won't be trees blooming in February this year across the SE US for the first time a good 7-8 years probably
  15. Ensembles overnight seem to have gone back to accelerating the return to a cool down again...problem is they do not agree on where the ridge is, GEFS too far west and we'd keep getting cutters but be cold...GEPS a bit better, EPS best...all have a +NAO
  16. The GFS finally came around to the idea of some snow...I'd be cautious somewhat about the "finger" band of snow...often times models do not see the coastal stealing the show just yet at this range...so anything over 2 inches with that feature is unlikely even if some runs try to show crazy amounts from it
  17. It did back when it was only ran out to 54 but I have found in the last few years thats less the case anymore....usually if the NAM has a semi wacky solution like it did at 12Z the RGEM will come out and look nothing like it...the fact they're both somewhat similar is interesting
  18. The GFS is basically the only snowless run at 00Z...just goes totally coastal dominant, even the 18z Euro did not do that so as of now the chance to end the streak does live on. If the Euro starts going bone dry even with the WAA then its probably down to 1/20 happening
  19. The GFS did not take long to look totally different than literally every other model with an EC storm lol....through the UKIE with just the Euro to go its basically the only model lacking any of that precip associated with the vort getting north of the MA...that said the GEPS sorta does say the RGEM/CMC are out to lunch on that idea more or less. I have not seen a ton of instances though in recent years where the RGEM/NAM being sort of similar at 84 has led to a solution not somewhat close to the idea...its usually 80-20 the NAM is different than the RGEM at that range
  20. Any time you have two storms tracking in close proximity relatively speaking and one is significantly large or strong there’s a chance you will have some impact on the forecast of the 2nd event so it’s not out of the question at all
  21. Yeah its about as close to no change as you can get, it was better ever so slightly in some areas, worse in others but it likely would not have unfolded much different than 12z
  22. At this range the Euro got schooled by the GFS if I remember right...it was pretty far east and cold, at least up in this area past 96 hours then was gradually coming west and milder. I was concerned about a snowier solution 4-5 days out because the recent year normally amped Euro with any east coast storm in that 84-120 period was not amped relative to the CMC/GFS at that range
