It’s only been a few days since the recent cut-off
After a fairly mild and mostly dry couple weeks for most of the South-Western Cape, things look set to change this weekend with the arrival of cold front, which looks likely to start impacting the province from Saturday afternoon to evening. Winds are likely to get stronger from late morning, peaking in the late of Saturday the 11th, however look to remain fairly moderate with gusts likely to remain under 40km/h.
While light rain can be expected in the initial stages of the front, the current 00z GFS (9 July), shows the bulk of the rain occurring late on Saturday or into early Sunday morning with falls in excess of 20mm possible. Temperatures will also begin to drop late on Saturday and into Sunday, with freezing levels dropping to as low as 1200m in parts of the province later on Sunday.
Snow can be expected Sunday on the mountains of the SW-Cape and the latest model forest showing that early on Sunday morning will be the most favourable time for snow to fall, with moisture becoming more limited later in the day, despite the freezing temperatures dropping throughout Sunday, should more moisture than currently forecast be present later on Sunday, we could see more snowfall than currently expected. Temperatures will remain very low on Sunday as the cold front passes through, as well as on Monday morning in the wake of the front where minimum temperatures below 0 are possible in the Northern Cape.
While the Western Cape looks to receive the bulk of the snow for this system, there remains a small chance for isolated snowfall into the Eastern Cape, as well as the potential for some light snow in Lesotho on Monday.
Updates will be made to this article should the models show any significant changes over the next 48 hours.
