  2. Spc: Northeast... Scattered thunderstorms should develop later this morning into afternoon, over the mid/upper Ohio Valley and Lower Great Lakes regions. This activity should pose an increasing threat for hail, damaging to severe gusts, and a few tornadoes as it moves eastward across the outlook area, with the greatest threats in and near the "enhanced" corridor. This will occur as large-scale ascent, deep-layer wind profiles and vertical shear all strengthen ahead of the Great Lakes shortwave trough, and perhaps ahead of an eastward-moving MCV or convectively enhanced vorticity lobe from morning activity over IL. These processes, occurring along and ahead of the surface cold front, may support multiple rounds of convection. Activity will impinge on a diurnally destabilizing and favorably moist boundary layer, commonly characterized by surface dewpoints in the upper 50s to upper 60s F. In addition to heating, moist advection ahead of the convection should help to: 1. Strengthen buoyancy over areas of PA/NY now containing more modest theta-e than in the Ohio Valley, and 2. Offset vertical boundary-layer mixing enough to maintain or even increase preconvective dewpoints farther west. MLCAPE in the 1500-2000 J/kg range should become common, in a supercell-supporting kinematic parameter space of 40-55-kt effective-shear magnitudes. Though near-surface flow may be weak, veering with height and hodograph curvature should be greatest near the NY/PA border and into western NY, with effective SRH in the 150-300 J/kg range. Analog soundings and a 2-D hail model applied to forecast soundings each suggest significant-severe hail may occur, with the risk of a few such reports now appearing large enough to draw an unconditional area. Otherwise, the wind and tornado threats largely appear to be similar to those described in the previous outlook, with minor adjustments made for more-recent progs of convective trends.
  3. Wow huge collapse in the line
  4. Macys got some thinking to do now, do they want people lining up in thunder storms?
  5. Rain doesn’t seem to be a big deal on Saturday anymore
  6. Waves crashing over the seawall along the belt parkway by the Verrazano bridge
  7. Gusting around 30 now and consistently getting stronger
  8. Gfs now showing those crazy wind gust the nam and hrr are showing overnight
  9. Most models now have a big burst of wind from midnight-6am I guess they’re seeing some convection mix down stronger winds
  10. Nam has winds picking up around 7pm with gust 70-80 overnight, so overdone lol
  11. Just a link for everyone if they wanna follow https://poweroutage.us/area/state/new york
  12. Most models have nyc east meeting High wind warning criteria, gust 55-65 highest further east. A lot of the models also now focusing on a period of strong winds overnight and another mid morning early afternoon tomorrow. Not sure if there’s any inversions or what not just going off the output
  13. Hrr has some wild winds nyc east overnight into the morning
  14. Nam showing strong winds starting around 9pm tomorrow night again
  15. Hrr has impressive winds starting Thursday night as well
  16. 40-60mph wind gust across majority of the north east is pretty impressive it’s been a while since we had a widespread high impact wind event
  17. Upton Winds will also be an issue as the NBM and its 50th percentile show 35 to 40 kt gusts across the area on Friday, as SE winds steadily ramp up ahead of the warm front. Winds will veer around to the S/SW in the afternoon and then W following the cold frontal passage late afternoon/early evening. Gust up to 40 kt will be possible throughout the day and even 1-2 hours behind the cold front, then gradually subside Friday night. There is lower probability of a high wind event (>=40kt, >G50kt), but cannot be ruled out.
  18. 50-60mph gust every model locked in
  19. ? Every model has winds into the 50-60 range yes the 70 is over done but 50-60 is a significant event
