So all that and no storms? What happened?

We had all the ingredients we needed in abundance: moisture, heating, instability, increasing winds above the surface. We knew we would have all these severe thunderstorm ingredients at the ready today. (1/4) (2/4) Well then, why no storms?

We anticipated storms to focus along the dry line, a boundary between very dry air & very moist air. The dry line moved across MO as expected but we didn't have enough air colliding at the surface to rise and form thunderstorms!
