Spider ID Needed

This spider was found spinning a web between our front door and the deck railing. I became frustrated trying to find an ID on this arachnid. Included below are additional photos of top and underside views.

If you have an idea as to the name of this spider, please leave a comment. Simply click a thumbnail for a larger view. Once the shadowbox opens, you may expand the view by clicking the expand icon in the upper right hand corner.

Thanks for your help!
