  1. Its sort of February 2003 but with a strong surface low and a more dynamic setup. That storm was purely overrunning
  2. Canadian really the only Monday holdout now. Still suppressed
  3. Sure enough ICON came in colder Wednesday
  4. Its because it has a "bomb" for Monday in relative terms. Its like low 990s off NJ Monday
  5. It definitely hurt ratios in the 12/26/10 event. The thermals indicated should have been 12-14 to 1 and it was only about 9-10
  6. If that came to fruition I would not want to be in places like interior MA/North of SWF/NW CT for Wednesday. The stronger Monday is more likelihood Wed could be mostly a NYC south event
  7. Real close. NAM for LGA shows about 37/30 37/29 when precip arrives. I still think its just a hair too warm. Would need to see those DPs be more in the lower 20s. There is no question the arrival time of the event mid to late morning which allows for clear skies the night before and prevention of any heating during the ensuing day helps
  8. I think he’s just saying the system would track more tucked with a weaker PNA. The ICON verbatim would probably still be 5-10 inches of snow for anyone north of Sandy Hook and west of Islip before they changeover over but the ICON of course doesn’t resolve the cold air correctly and has like 1 hour of snow. This event barring some sort of massive change in several parameters even if it flips to liquid will probably be in the category of a January 87 March 93 February 2014 in regards to how much snow you see before a flip
  9. The event seems to have transitioned from almost an anafrontal feature to a full surface low setup which might provide better rates and lifting but it’s still very marginal for NYC. Seeing both NAM/GFS showing spreads of 40/29 or so before precip commences just isn’t really that good. Seems like it might be snow but that It’ll be 35/34 the entire event. This is an event where snow maps will badly fail
  10. Given the air mass in place and the setup this thing can basically track just east of Montauk and the only places that would mix would be the Islands and maybe parts of the Cape
  11. CMC whiffs. Basically only model so far at 00z to go flatter
  12. My guess is the GFS doesn’t budge on Monday (it’s a classic type event where the GFS is a holdout til the last minute) and it ends up fairly similar to prior runs for Wednesday less amped than the Euro
  13. It just erodes the CAD signature over places like EWR in 2 hours which wouldn’t happen
  14. The icon finds a way to erode a CAD signature in 2 hours with the Wednesday event. Even if the track happened you’d snow for longer than that
  15. The icon basically finds a way to make the warmest solution overall from DC to NYC given the pattern. You couldn’t duplicate that in real life if you tried with the surface and upper features where they are
  16. Not just that it basically finds a way to make the rainiest or warmest solution possible given the pattern. It’s sort of funny.
  17. This feels like the first time in 5 years where at this range the other models moved towards an amped Euro solution vs the Euro caving. It seems anytime since 2015 the Euro was outlier amped at 72-90 it was wrong
  18. Icon NW too. This has to be the first time in ages where inside 90 the Euro ended up not being too amped and other models moved towards it vs the other way around
  19. The air mass just isn’t that good. It’ll be a very narrow corridor who gets hit with decent amounts Monday. If the air mass was even 3-4 degrees cooler in the 850-1000mb layer this would pretty much be a snow event across the board
  20. The November 2018 event was what we call the due north overrunner when we did storm analysis. I don’t know how they performed for you guys but for the NYC metro any event that comes up straight from the south with a high center near PWM ends up much snowier than expected because you get banding features and the cold air holds longer. 12/14/03 2/13/14 and 1/22/87 are other examples. 87 was more a classic Miller but the track was almost on a 180-360 angle up the coast. There is absolutely a difference in isentropic glide features when it’s coming from that direction vs 220-040
  21. It’s unlikely. The only way this probably could occur is if somehow the main shortwave responsible for the Wednesday event is being grossly overestimated by guidance. Otherwise the Monday event being big seems to translate strongly in most ensembles as PSU saw to being a good indicator for Wednesday
  22. You want the Monday event to be more amped. Even if it’s rain in most of the area. PSU in the MA forum went through ensembles on the GFS and Euro and found almost unanimously the members that are amped Monday have the best solutions for Wednesday. The only place which probably doesn’t want Monday to be amped are places like interior SNE such as Worcester
  23. The SREFs at 21Z (if anyone uses them anymore) are quite a bit wetter than 15Z
