Storm, prairies, and the sun

Yesterday, after I returned from work, I had my whole evening planned.  Basically editing, editing, and more editing.  Around 7:30pm that evening, it became apparent that I will not be accomplishing my goal.  Simply because the skies turned into a spectacular light show.  I quickly grabbed my camera, Cokin filters, and off I went.  Here is what the sky looked like last night.  Enjoy!
