  1. Not many events here go RA-FZRA but March 96 we definitely had one...not sure what the day was but the setup I'm sure was probably close to this
  2. Yeah my uncle in Quogue over a few blocks from KFOK got 24...there were some big amounts there south shore but not many reports. I think Blue Point had 22
  3. Yeah the GFS/GEFS has largely been more SE ridgy overall D5 and beyond last few runs than the EPS/GEPS which is odd given it cranks the MJO into 3 and many other MJO guidance plots showing nothing like that
  4. their storm total should be 8.7 as of 1pm as they reported 7.5 at 1pm and had 1.2 yesterday. The 420 climate report though has 7.3 which makes no sense...should be about 8-8.2 for today as both LGA and JFK added around 0.5-1.0 from their 1pm total
  5. Ratios were around 11:1 based on the NYC measurement.... .69 liquid today 7.5 inches
  6. thats just today...its 8.7 for the event which is close to EWR/LGA
  7. Normally it happens in a transfer scenario but these lows we’ve seen in recent years like this probably are some product of the crazy warm WRN NATL SSTs/WAR/AGW issues is my guess because they’re a recent thing
  8. The few cases we’ve seen in the last decade where this was modeled the end result was often in the middle where there was a secondary low but you didn’t see the massive pulling of the precip field with it
  9. That’s about right. The far NW could be too high but a shift of 25-30 miles which is a logical error in this range will be a big difference if you’re from nassau back to the west edge of the area
  10. The RAP usually has a west bias at this range but it’s so far west there is room for a drift east if it’s got the right idea
  11. UKIE historically has had slight progressive bias with monster lows like this below 980 so it fits about with that with most other models now somewhat left of it
  12. Thats very much a mesoscale feature...the GFS is still a bit low grid to see that
  13. 0 is unlikely but 2-3 sure could happen in a worst case scenario
  14. there was a storm a few winters ago where that happened and then at the last minute they all lost it. I don’t remember which it was but the forecasts all busted too low as a result of it
  15. This looks like the usual GFS last minute cave...at the same time I don't think this will be a case where we see the PA/NJ border end up getting 10-15 inches as we've seen in some prior cases like this. I would say NYC ends up around 8 in the end so maybe something near the NAM/RGEM idea now
  16. Its done that often in these events...it does not cave til 24-30 out and even then it sometimes is too east. In this case the mesos are not quite as far west as they were in many cases I remember so maybe it won't be quite as wrong but it seems at this stage it'll be wrong on its idea vs the Euro/CMC/RGEM overall
  17. It used to have a consistent east bias with very strong coastal lows or lows sub 985 or so and tended to be very good with anything weaker but it had an upgrade in 2014 and it has been erratic since but still will tend to have a bit of a progressive bias with stronger systems
  18. Yeah if you extrapolate it it does seem that it moved west
  19. The UKMET appears to be fairly far west on that one site that comes out early but its hard to tell
  20. The GFS usually holds out til the final 30-36 in cases where its struggling with an East Coast storm...I expect you don't see any major moves til tomorrow
  21. This may be the usual adjustment followed by the slide back east, if we adjust for 2-3 more model cycles though we would be in decent position for a solid event even with a late tick back to the east
  22. The area doesn’t need a huge change to get a decent snow event unlike this last storm where we were largely out of it by this point. New York City with this event at this range is about where Raleigh or Salisbury was with the last storm. They were shown to get a big event 5-6 out then they were west or fringed. Ultimately they never got the shift they needed but they were in it til 48 hours out
  23. I'll take a wild guess and say the 00Z NAM is west of 18z but considering it was in Portugal at 18Z that is not a tough guess to get right.
  24. Probably not because winds will be really strong. Especially nearer the coast
  25. Any time the GFS differs fairly significantly from the Euro in a storm that has southern stream origin or anything close to it, its possible it will get owned. It did not last week but that was more of an atypical evolution. The GFS did badly blow the one true Miller A we had this year
