It's been a quiet summer as far as trough activity
The SAWS Aerosport spot-chart for latt 34S long 19E (near Jonkershoek) for tomorrow (Fri 29th) clarifies some things about the (early stages) of this event. There will be moderately heavy rain during the morning (spread over a period of several hours), following which it will become mostly dry.
The wind directtion will change to SW around midday, and the freezing-level will begin to fall drastically (from 3000m to 1600m) during the afternoon. However, this will occur after the front has passed, and there will be minimal precipitation during this stage. An unusual feature is a mid-level inversion, with slightly warmer air (0C to +2C) between 2500m and 3000m. Neither of these features is conducive to the production of snow over the SW-Cape mountains (on this occasion).
The situation further east (not shown) is rather different, with lingering moisture and cold air together producing light snow over the high peaks in the Swartberg Range (and further eastwards). This will commence overnight into Sat 30th, and will be discussed in more detail on this thread when further charts become available.
The outlook for snow over the E-Cape & KZN Drakensberg during Sat 30th remains highly favourable, though it is too soon to post details of the exact coverage and freezing-levels.
