  1. Interesting how whatever the effects that existed back in 1947 still exist today. LGA just can’t go below 37 (at least officially yet) Same thing happened the morning in 47 when all the stations set lows
  2. I doubt it. The wind flow is too WNW. The air mass aloft though does cool at 850 another 1-2 degrees or so. The best cold advection occurs the next few hours. I wouldn’t be shocked if NYC maybe got to 33 or EWR got to 33
  3. NYC has tied the daily record of 35 and LGA has tied their May all time record of 37 as of 2am
  4. 5/6/1891. Only time NYC went below 34 in May. All other records are 34 are higher and I think there’s just one 34 day
  5. I believe the NWS uses some sort of rule like if LGA/EWR report it they can report a T for NYC otherwise either ASOS has to have SN or UP at NYC. ASOS isn’t capable of a RASN or SNRA report
  6. LGA looks like they’ll easily break their all time record. Just need 36. I’m not sold EWR won’t make a run at tying their 33. Temps are definitely running under guidance almost everywhere so far
  7. LGA only needs to get to 37 tonight to tie their all time record. JFK should break their deadly record. NYC could tie though I would say it’s probably going to fall 1-2 short. EWR’s all time record is 33 on 5/9 so I don’t expect a daily record or all timer to be set
  8. I believe that it does. Someone showed me some station like Amarillo or somewhere reported 6 inches of snow in mid June once and it was hail
  9. HAHA. Get used to it. HRRR will replace NAM in next few years and run to 60
  10. There was a bad one in July 1997 too. Small area near Rockville Centre i think. The 95 one was pretty small hail
  11. I clearly remember that day, our roof took damage from hail in Nassau at like 11pm and that was also the day I believe the Pacers upset the Knicks in game 7 at MSG
  12. Yeah no way. I mean it could happen. The only areas that will see accumulating snow with this are those under a CCB or any area of frontogenesis with better rates. Given the way this whole thing is setting up I feel it’s unlikely at the moment that coastal areas would end up under that though it may setup more SE than the Euro and others have been indicating
  13. The 02 snow melted pretty fast. I went through ALB about 4 hours after it ended and you'd never know it snowed
  14. I think below 40 easily occurs Sunday AM on the setup at 168. Euro shows 35. GFS had 47 on the 12Z run but the Op run was an outlier on being too warm. The gradient is strong enough and 850s cold enough I could not see it staying over 40. Just might not make the record of 36.
  15. I find it funny how relatively mild or less expansive the 12Z Op GFS is with the cold this weekend relative to recent ensemble runs as well as the Op Euro or EPS. We rarely see the GFS be milder, especially when its inside 7-10 days.
  16. Its interesting when you look at the NYC record lows how after 5/12 there's a pretty good uptick with almost all of them jumping 5-6-7 degrees from the first 10-12 days of the month.
  17. The GFS/Euro wanted it to dig more 2-3 days ago taking the cold down into the TN Valley/SE region. That really is not realistic in May as most of those areas see their final FROPAs til September around this time. I think it'll be centered mostly DCA and north.
  18. I believe though that much like cold in late October/early November our weather now does not necessarily correlate to summer and may even be a reverse indicator. Look at 2005 for example. There are only a few years I remember where miserable springs carried the entire way through. 2003 was one example
  19. NYC would have a legit shot at their all time record for May if that played out. Only way it can be done is a deepening system with strong CAA and NW flow. They'll never sniff 32 this time of year without a strong gradient all night
  20. On the Euro NYC would likely comes close to their record lows on 5/9 and 5/10 of 35 and 36.. The all timer is not out of reach here if we get the right setup. Its too far out to determine but if we did get a coastal and had enough of a gradient with strong CAA 32 is not out of the question given the -AO/NAO
  21. If the 240 hour 12Z Op Euro verified there would be record lows and max mins smashed everywhere from Maine to Alabama and Georgia
  22. The good news is it'll change. Much like winter it seems if you're really cold in April/May you rarely have a cool summer. The only cases I know of where this really held the whole way through were 83 and 96 and I want to say 96 actually was fairly mild from 5/1-6/15 but it flipped right after that.
  23. Outside of mid August into September It only happens in non classic setups where you aren’t relying on heating instability ahead of a front.
  24. You don’t get many outbreaks in KS/OK/TX where you see like 50 plus tornadoes. It’s more common to see violent tornadoes though vs outbreaks with high numbers. Those are more frequent to the east as those maps show as well as further north in the Plains
