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!

(3/4) Sometimes that's all it takes, one missing ingredient and the day looks completely different than what we expected.

(4/4) Take aways from today: are you prepared for the day we do have all the thunderstorm ingredients in place?

-Have a way to get warnings, even at night
-Have a weather safety plan
-Know when to put your safety plan into action
