  1. For tomorrow from the SPC ...Appalachians/Upper Ohio River Valley and Mid-Atlantic States... Widespread convection within a moderately sheared environment will create the potential for a relatively active severe weather day across portions of the Appalachians/OH River Valley into the Mid-Atlantic, but poor midlevel lapse rates and the impact of early day precipitation/clouds on destabilization may tend to mitigate this threat to some extent. The severe threat should begin to evolve by late morning/early afternoon, as midlevel flow and effective shear gradually increase and pockets of heating/destabilization develop in the wake of early morning convection. Thunderstorm redevelopment is expected along the cold front pushing into western PA, and also across the higher terrain of the central/northern Appalachians. Effective shear of 30-40 kt will be sufficient for organized multicell clusters and perhaps a few supercells. Corridors of locally damaging wind are likely to be the primary threat, but a couple of tornadoes are also possible, especially with any supercell that interacts with differential heating boundaries that may evolve through the day.
  2. I saw that one and questioned it too. I think they have since cancelled it. I still haven’t received a drop of rain .
  3. Yea could really see the storms pop up on radar along the gust front. Pretty cool stuff .
  4. Im always so fascinated and yet so confused with storms like tonight. I never understand the dynamics that cause the complex movements of thunderstorms like tonight.
  5. Also some flooding in Lebo. Cedar blvd, right in front of the entrance to the park is under water. One car was stuck in there about an hour ago
  6. How did you fare? Looked like so nice velocity reading around McMurray. I had great thunder and lightning some moderate rain but hardly any wind. I was just north of it. .
  7. Not feeling too optimistic about the storms making it to us intact. Satellite imagry showing that the storms are having a hard time maintaining after they form. CAPE looks decent, but the aloft winds are pretty weak. I'm hoping to get some good thunder later tonight, but not holding my breath.
  8. NWS Pit has 8 tweets over the last hour talking about the rain in the south hills. They also retweeted the Allegheny County handle. Maybe could have done a little more, but i think thats a pretty good showing.
  9. Just took a peak at that cam. It does a live stream from it as well.. Crazy high water down there right now. Stay away if you can
  10. I'm just amazed that all of a sudden the cells popped up on what looked like a line and then stayed stationary. Crazy stuff. Areas south of downtown received 2+ in of rain in an hour based on radar.
  11. Anyone smart enough to figure out what was the trigger this evening to cause those storms to go up?
  12. I’m on the outside part of that cell. It’s been raining for almost an hour and my gauge has almost a half an inch in it. .
  13. The cell that just appeared over AGC is dumping rain. And it’s not moving. .
  14. This incoming line is really losing its punch. Just some weak showers to roll through I think. Even the back end of the rain is shrinking. On radar it looks like it is racing to catch the leading edge.
  15. I noticed that as well. Do you think topographic enhancement had anything to do with it? Needing the mountains to get things going?
  16. https://lmaps.org/#-80.59;40.18;9 In case anyone wants to watch the lightning strikes. Seems like a cool website.
  17. That warned cell in Washington county looks nasty. Could be some decent hail stones in there.
  18. Checked this morning. Enhance risk shift east. Firmly in the slight risk Zone for the area. .
  19. A little windy here, but the main part of the squall pasted to my north .
  20. Nice squall line starting to form. Meso Discussion is mentioning the impressive lapse rates coming out of Ohio and into Western PA. Should allow for some nice wind to mix down to the surface with the squall line.
  21. I remember this storm. Fortunately, I go much higher numbers than this. But i know some people in our thread got 2ft+
