6/8/10 Chase

After a long hiatus, Chris and I have decided to chase today. Even though the set-up is less than perfect, and something I definitely wouldn't drive to OK or TX for, it is good enough to warrant a chase. We are going to be chasing in Missouri for once. Our target area (north central MO) is only 3 hours from home. When there is potential action so close to home, why not chase?
The main thing I am worried about today is the MCS that is currently stretched across MO. How much destabilization will occur in it's wake? And what sort of boundaries is it going to leave behind? The current model runs are suggesting that the atmosphere should destabilize this afternoon to the tune of 2000 j/kg of CAPE. That moderate instability coupled with 35-40 knots of deep layer shear should be sufficient for supercells in a very weakly capped environment.
The lack of a cap has me worried as well. I am afraid that once storms begin to form, they will continue to form quickly and will rapidly develop into a line. Given the low-level shear that will be in place, the line could very well spawn a couple tornados. However, chasing tornados in a line is neither easy nor fun. If things do end up going linear pretty quickly, I hope to get some good shots of the shelf cloud as the complex propagates eastward.
