Here are some that I've taken from my iPhone
This one was taken on Sunday April 17th around mid morning as I was riding in a car from Hayward,,WI to Eau Claire, WI. The clouds continued to break into smaller pieces as the day continued
This one shows a beautiful front on Thursday April, 14th. This winds (shown by the flag in the picture) were strong and from the east. This picutre show three different clouds types in one sky: the altocumulus in the upper left, the altostratus in the bottom left, and the blanket of stratus clouds on the right.
This picture is from the 4th of July, 2010. I love this picture because you can see the beautiful cumulonimbus cloud building in the west. This picrture is from Excelsior, MN which is right next to my hometown of Shorewood, MN. It did not rain at the time of this picture it passed over us before it released precipitation.
I took these two pictures while driving through Des Moines, IA while on a trip to a regional conference in Lincoln, NE. It shows some altocumulus clouds.
I took this picture on Friday, May 6 over the Chippewa River over near the Water Street area of Eau Claire. It shows some cumulus humulis clouds.
I took this picture on Saturday, May 7over the Chippewa River and the Downtown Eau Claire area. It shows some beautiful cumulus congestus clouds during the sunny warm day.
