Looking through the past couple events 2009 seems to be lacking something in the tornado market. What it is isnt exactly clear! Most explosive events with what seemed to be adequate shear have failed to produce with one or two exceptions. What it seems to boil down to is a lack of significant surface features. and when there seems to be adequate moisture the winds are lacking. The past two events that should have held high tornado potential specifically June 7th and June 5th which did yield a tornado before the cells were rooted on a cold/stationary front. June 7th seemed to yield the same results. With cells going up then moving into unfavorable air. Which is highly unlikely for a triple point event. Cells normally go up then move into the warm sector. With these events they seemed to take paths that lead them in the other direction. The lack of surface winds on the 7th really made a difference. It seemed the instability was obviously good but the cells on the 7th lacked good low level rotation. And maybe even in the lowest 1km.
It seems that 2009 is going to continue to be a frustrating year. Where most other years seemed to get better later on. Its interesting to study such cases in detail which I have yet to do. But its always a nice contrast from a learning perspective.
