    Isolated supercell going up SW of OKC near Hobart.

    First wave initiated early, before LLJ cranked and helicity values peaked. Those things are happening as I type this….reason why I will say, yet again, the forecast was for 9pm-4am. Midnight is the sweet spot in the timing.

    No, not everyone. Just certain people who scream bust before they actually read the forecast details.

    Again…come back and scream bust at 4am-5am. Bulk of this threat was forecasted to be nocturnal, around midnight. Some people need to learn basic reading skills and comprehension before posting.

    No, it does not. There’s 2 waves of supercells. First wave blows through, second wave overnight is what this whole forecast entices. This High Risk is for overnight/nocturnal activity. Scream bust if there’s no tornadoes in central OK by 5am. Really, the timeframe is looking to be 9pm-4am.

    Shouldn’t the thread headline read “5-6-24” instead of “4-6-24”?

    This might be the single most violent motion I’ve ever seen documented.

    My understanding is that it is still preliminary. I believe Tim Marshall is going to Elkhorn tomorrow to survey. He was in Marietta today and his findings at the Dollar Tree Distribution Center was the reason that tornado got upgraded to EF4.

    Though DOW measurements are not used in the surveys, this is a pretty impressive measurement. DOW measured 224mph winds inside the Harlan, Iowa tornado at its peak Friday night when crossing 59. Seems plausible surface winds were between 170mph-190mph.

    4000+ SBCAPE along the OK/KS border. Latest guidance showing a string of pearls. Supercells maintain separation and intensify as they enter into the Moderate Risk hatched area. Nadocast really starting to go bonkers. Will be interesting to see what the NWS SPC does at next outlook.

    Really got a bad feeling about this setup today. Everything seems to be coming together in all the wrong ways.

    I absolutely agree with your analysis so far. If storm mode is not messy later today, this environment has the hallmark and look of a classic tornado outbreak. Hard to imagine it surpassing what we seen yesterday. However, the parameter space is more significant. Very possible if things come together this could be a Friday repeat but over a much larger areal capacity.

    This shot from Storm Chaser Freddy McKinney, mark my words, will be in the history books. What a monstrous, powerful, and truly violent tornado. Photographed right as it peaked in width and intensity. This shot has Rochelle, Illinois vibes.

    Depends on the construction of the house. A poorly constructed house can be leveled by an EF2/EF3.

    Tornado intensity sheets can be generated through the NWS and NWS SPC websites. There actually might be some radar software that allows you to generate this. If I’m not mistaken, GR Level can populate this data sheet as well.

    Radar estimated intensity for the Bennington/Blair tornado

    Minutes ago, looked as if there could of been a trio

    Historically violent tornado….images are for the history books
  22. WxSynopsisDavid
    212mph gate-to-gate minutes ago

    Minden, IA tornado peaked around 185-200mph. Debris ball was indicative of 3mi width. Debris ball was very large with debris being lofted well out ahead of the tornado. Classic multiple vortex based on videos I’ve seen on Twitter.

    Btw…can anyone confirm if the Calhoun Nuclear Plant was damaged?
