What you have there is what is commonly called a 'crusifix spider' araenus diadementus I think , its been a long day  so i am not quite sure on the latin name but 'pretty' sure
its called that because the white spots on it back roughly form a crusifix
during the day they usually have a retreat that they hide in
you should be able to find her during the day by looking for a thicker 'line' from the center of the orb
Be careful though these guys have chelicerae that are quite large and can easily pierce the thickest hands
In the evening throw a small cricket in her web and watch her go.....man its really neet <img src="http://www.faunaclassifieds.com/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=''>
hope this helps

I have a few of these under my deck , very cool looking spiders, i'm gonna try throwing a cricket in the web tonight

It could well be Araneus diadematus, the cross orbweaver, but it could also be a Neoscona sp. My confidence level is not high, I'd need some more close-ups to give you a better answer.
