This close in do yourself a favour and use the best cloud models available to Aussies from our own BOM guys. Phil Hart recommends this and its definitely worth figuring out what the various options offer. Doesn't look like there's an option for Adelaide area, so Access-A the next best option.
Its very rare these models don't offer amazing fidelity for predicting cloud movement. Skippy, 7T and others use the excellent NOAA data which is a great backup/confirmation but not quite as "hi res".
