  1. 6-8 in NYC is a KU this winter and they probably could still manage that out of this.
  2. You'd rather be in PHL-NYC now for this than BOS/DCA. Its fairly rare we ever say that but this is a setup where at least at this moment that corridor is more likely to do well, BOS would have a chance to improve on their prospects than DCA
  3. BTW I really doubt LGA/NYC west ever go to rain, so -FZRA/PL unfortunately is likely, hopefully it will be light but if the coastal continues to tick a bit more west and higher QPF makes its way in we could get a tenth of ZR...ideally we'd want to keep it sleet. JFK east I think goes to rain but 030-050 winds on almost every high res model for LGA/NYC won't flip them to rain
  4. These types of weaker events with overrunning can still bust pretty significantly on the high side, even today. These ALWAYS busted 25 years plus ago because no models had the resolution to really resolve the lift/banding but even now the weaker events they can miss those types of nuances that the high res models capture in a case of stronger overrunning/WAA. I am sure someone sees crazy amounts here where they stay all snow...near the city we'd need pretty solid banding overnight to go over 3-4 probably
  5. It is not terribly different than either NAM...the HRRR beyond 12-18 I would avoid for convection or cases of warm air aloft with ZR/PL. In this case though the changeover should be towards the tail end of the run and it shows a similar evolution to the 3km NAM on that anyway. I just always warn its usually too cold in the mid-levels
  6. 12K I feel does better in the 36-48 period...3K I like o 24-30, not much beyond really
  7. I was trying to think of an event this reminds me of and I cannot think of one at all. This is sort of a 1980s type snow event here which is probably why I cannot remember
  8. One thing to watch, the 18Z HRRR showing that snow earlier than any model tomorrow for CNJ-SNJ...that could be 200-250 jet induced...the HRRR has captured a few of those events before with snow...one I think occurred in the 20-21 winter here and it had it better depicted than any other guidance
  9. 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
  10. 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
  11. 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
  12. 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
  13. 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.
  14. 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
  15. 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
  16. 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
  17. 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
  18. 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
  19. 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
  20. 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
  21. 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.
