A lack of jet stream support and stronger vorticity values is leading me to assume that this will not be a big event. I am not seeing sufficient jet stream winds to indicate that this storm will be strong enough to cause a more large-scale event, and that this may be a slightly more localized event.
When it comes down to it, the instability will probably cancel out the cap and ignite some storms. The question is, will these storms be severe, and could they be tornadic? I would not go as far as to forecast that, but using these indications, I would say that some severe storms are possible, but lack of major shearing is discouraging for tornado potential.
