Randall,
It looks like the location in your NWS link is Lat: 32.418732790609056 and Lon:-111.05851113796234, but the CWOP location being shown for DW4959 is Lat: 32.18523, Lon: -111.0772. I'm not sure which one is your old and new locations, but my guess is the CWOP location info hasn't propagated your changes through the system yet.
