Latest indications show high temperatures and dewpoints covering the whole of the Ohio Valley, but the highest of both in the red box. Instability at the surface accumulates to a fair 2000-3000 units of instability- more than enough to fuel strong storm cells. There is a next to nothing tornado threat per latest observations, and lack of high wind shearing should keep it that way. However, I am seeing small pockets of fair wind shear, which may lead to a brief spin-up at the most.

Hey Andrew, do you know how to read crossover charts? I can't find squat. If you do, what is the rule of thumb? What angles should each pair of barbs be at to catch interest? Are they good for indicating possible shear? Thanks
I can't say I have the gist of them either, but I would say different wind speeds and fairly different directions in both barbs will indicate a good environment for some rotation.
