Given the magnitude of the low level and bulk shear, CAPE like that will be more than sufficient (300-500 J/kg probably isn't going make a whole lot of difference), any breaks in the clouds will obviously exacerbate the situation.

Andy, I agree that's why I said that storms could get nasty along the northern edge of the best instability.
