I think it is possible to enter the zipcode and then have the user inputed zip code forecast to be parsed like the local forecast and then be dispayed on my website instead of leaving to the NWS
That's what HAMweather does. You can customize the output to exactly match your web site's look just by modifying a few templates. Plus it displays watches/warnings, radar, area forecast discussions and more... all based on the zip code a person enters.
