  1. Video of an apparent tornado in Lebanon earlier today https://www.facebook.com/100009682356689/videos/2668568046777171/
  2. What an insane day it turned out to be. My post about this being more so a "damaging wind" threat did not age well. This ended up being a localized tornado outbreak for SE PA and Southern Jersey. I actually went to chase the two tornado warned storms in northern MD and ended up missing them, started to drive back and was getting phone calls from my friend in Levittown who was chasing that New Hope storm. He then backtracked and tried to intercept the Bensalem storm but missed that one. Overall, just an incredible day. Low level shear for the win, sun/CAPE for the loss. I hope everyone here on the board and across the area is okay.
  3. Video of a Lebanon County tornado earlier https://www.facebook.com/100009682356689/videos/2668568046777171/
  4. Yeah the hook on that storm is something you don't see often around here.
  5. Those storms in Bedford county, entering Fulton, look to have that discrete/curvy look to them. No warnings on them though
  6. * Tornado Warning for... Southwestern Somerset County in south central Pennsylvania... * Until 245 PM EDT. * At 212 PM EDT, a severe thunderstorm capable of producing a tornado was located near Seven Springs, moving southeast at 25 mph. HAZARD...Tornado. SOURCE...Weather spotters reported funnel cloud. IMPACT...Flying debris will be dangerous to those caught without shelter. Mobile homes will be damaged or destroyed. Damage to roofs, windows, and vehicles will occur. Tree damage is likely.
  7. The latest 1800z Mesoanalysis basically shows almost any CIN eroded. SBCAPE up to 2000 J/kg for much of Lancaster/York/Adams and MLCAPE up to 1000 approaching ~1500 J/kg. Bulk shear has very nicely increased as expected. Low level lapse rates have been increasing as well, LCLs are low (support tornadoes). So while CAPE is certainly not incredible by any means, it should get the job down with the ample shear. Damaging winds will be the primary threat, maybe an iso tornado later
  8. There's a tornado warning out in far western PA for a lone supercell *Reported funnel cloud with it too
  9. Another tornado warning out in western PA for Westmoreland and Fayette counties
  10. I don't expect the tornado threat to end up materializing, but I could definitely see a bow echo roll through the Philly area similar to last May's event, maybe not to the extreme that was. But even with all of us socked in clouds, the CAPE values should be sufficient enough to support some severe storms and the deep layer shear will help to maintain any line segments. We shall see, I think the NWS and SPC did a great job with this expressing the possible dangers of the event, while also recognizing the chance of failure as well. We might be leaning more so towards "failure" here, but that's what comes with living in this part of the country.
  11. Latest 1630z outlook still has the enhanced risk, shifted the tornado threat furthest east to the coast.
  12. Tornado warning for far NW PA in Erie and Crawford counties
  13. I can't pull up any current skew-t data (which sucks, MDT should send up a weather balloon lol). But the latest 12z 3k NAM has plenty of deep layer shear and a TOR sounding for the MDT region. In layman's terms... atmosphere go spinny, just need some sun...
  14. Latest 1500z update has MLCAPE continuing to grow. Up to 1000 J/kg across Lancaster and a pocket of 1500 J/kg across the Chesapeake Bay. Those values will continue to spread north as the low-level clouds wear thin and the warm front lifts north (hopefully).
