Gordon Richardson had the following to say in the forums
The 12Z GFS run (Sat 9th) shows a less extreme outcome (particularly over the interior of SA), though still a significant weather event.
It will be a long time before the models converge, and a definitive scenario can only be given in a few days time.
Edit: The 12Z GFS ensemble shows very slow convergence, consistent with varying extreme outcomes (or just a normal snow event).
