Pinpoint accuracy in the spatial sense isn't what's useful here for weather forecasting - it's the increased resolution for detecting subtle features and the increased frequency for detecting said features more quickly. This likely won't help improve "will it rain this afternoon at the golf course" forecasts, but it will very likely drive "we detected a thermal couplet on this supercell, let's tornado warn it" type decisions several minutes sooner.
