Not really a chase, just a bored Sunday evening and some storms backbuilt from Iowa. I drove west toward Fremont on highway 91 from Blair. North of Fremont one of the three single cell storms had a lowering. I thought it was a wall cloud at first, but soon noticed it was getting bigger and pushing ahead of the storm. It was the beginning of the outflow process. I moved south of it and paralleled it moving back to the east. In this pic it looked really nasty, because it was backlit.
The storms didn't do much more than rain and blow pretty hard. The show didn't start until the storms moved south. I noticed these mammatus after coming up from the basement at home. Wow, I could have missed my first impressive mammatus.
These looked so awesome in person. I know these pics aren't the greatest(they are video captures). This is one time I wished I had my canon rebelX back. I did have a pretty big goof while tapping these. A couple friends joined me on this hill in town while I was tapping these. At some point I forgot to hit the stop recording button, so I recorded a bunch of ground. Then when I went to tape again I thought I would be hitting the button to start, but unknowingly I was already recording so now I would be stopping it. I got about 10 minutes of grass and feet.
There was a ton of left over moisture blowing back to the northwest, just under these mammatus. From time to time you couldn't even see much of them.
