most of the ones i've found use xml, and id rather just use the JSON objective c source code.
Any suggestions?

Weather Underground has an API that returns JSON and XML. Fair pricing, plus 500 free developer calls a day. Weather Underground has many local weather stations outside of the NOAA official stations, a good number in the SF area.
