Omaha Tornado Chaser: Evening lightning pics

i've added some pics that i took of a storm that formed west of town about 30 or so miles. it was kindof a cool scene. i knew there were some storms west and southwest of town that were moving south, so not towards town. so just before sunset i went out on our back deck to see if i could see any lightning. there was a little bit that was being blocked by trees but i also saw a pretty healthy looking developing thunderhead off to the west as well that wasn't producing any lightning. i thought i would go west on fort to 156th street where there is a high school that has a nice parking lot and it sits high enough up that you can see a long ways to the west. as i was driving the little sliver of the moon that is remaining came out from behind the departing thunderhead just as i got to my parking lot. the first couple of pics were just the moon and the storm clouds. but then within 5 minutes the thunderhead suddenly started to produce lightning. it became more and more frequent, and almost immediately i started to see these "finger" lightning bolts that would actually shoot out from the tower to the side into the clear blue sky that was behind it. unfortunately i only got one of these and it was fairly faint on the camera, which is another reminder that i would really like to get a better camera that gives me more options on a night like this!
