My guess would be that the tornado threat will be less today and tonight, but i thought that Saturday night as well. The SPC doesn't even have us in the tornado threat today and tonight. They did have us in a 5% range saturday. So who knows. I will say there is not as much shear (right now) as there was saturday but this could change as the front approaches.
The radar is already lighting up across the region. with strong t'storms. That goes to show how unstable the atmosphere has become through the day. It should still be moderately unstable into the night time hours.
Tonight my guess is that this maybe more of an all around severe weather event instead of the bulk of it being in Ohio. The storms will also be isolated so they will be likely strong to severe.
Again i am only guessing. Becuase i am not a meteorologist don.t take this for an offical forecast. Just trying to build up the discussion.
