There is still some time before landfall (36 hours), but this morning's 06Z GFS model run (Thurs 30th) continues to show highly favourable conditions for snow below 1200-1400m over the SW-Cape (Boland and Overberg) mountains early on Sat 1st.
The GFS snow accumulation parameter (not shown below) indicates at least 5cm of snow over the SW-Cape by 06Z on Sat 1st. Much more snow is likely over the high ground (1600-1800m), due to orographic effects (and limitations in the GFS terrain model).
This custom GFS chart shows the likely precipitation between 18Z and 06Z on Sat 1st, as well as the freezing level at 00Z. I will post a more detailed chart closer to the time.
