The South African Weather Service (SAWS) has warned South Africans to expect possibly the coldest weekend since the beginning of the year.
Wednesday weather forecast
According to the weather service, a cold front will move over the south-west coast of the Western Cape by Wednesday afternoon, with rain spreading along the south coast and adjacent interior in the evening.
Gusty winds of 45-55 km/h can be expected ahead of the cold front over the interior and south coast of the Western Cape as well as the interior of the Northern Cape. These conditions may enhance the risk for veld fire development.
Warm to hot conditions are expected ahead of the cold front (due to offshore Berg wind conditions) especially along the south coast of the Western Cape and the coastal areas of the Eastern Cape.
Gauteng residents can expect partly cloudy and cool weather, with isolated showers and thundershowers from the afternoon.
Thursday weather forecast
According to the weather service, a steep upper-air trough system will develop into a cut-off low pressure system over the north-western interior of the country by Friday.
Bitterly cold conditions are expected to move in over the western and southern parts of the country
during Thursday, spreading to the central and eastern parts by Friday and Saturday.
Maximum temperatures are not expected to exceed 14°C over the interior of the country, with maximum temperatures barely able to reach 8°C over the high-lying areas of the Eastern Cape, the south-western high ground of KwaZulu-Natal and the south-eastern and extreme southern Free State during Friday and Saturday. Small stock farmers have been advised to take the necessary precautions.
Widespread rainfall can be expected over the southern and central parts of the country from Thursday onwards, with light snowfalls likely over the mountainous, high-lying areas of the Western and Eastern Cape, spreading to the Lesotho Drakensberg regions by the weekend, where heavier falls are anticipated.
Light snowfalls can also be expected over the high-lying ground of south-eastern and eastern Free State. 24-hour rainfall accumulations of 25 to 35 mm can also be expected over the drought-stricken parts of the Eastern Cape.
There is also the possibility of isolated severe storms, accompanied by strong winds and large amounts of small hail over the central and eastern interior.
The upper-air trough will intensify during Thursday, causing widespread rainfall over the eastern parts of the Western Cape and the western parts of the Eastern Cape.
A yellow level 2 warning for disruptive rainfall, resulting in localised flooding of susceptible roads and bridges as well as flooding in informal settlements, can therefore be expected in the aforementioned areas, spreading to the central and south-eastern parts of the Eastern Cape during Thursday.
Friday weather forecast
Due to the lowering of atmospheric freezing levels, combined with abundant moisture in the lower layers of the atmosphere, snowfalls as deep as 2 to 5cm can be expected from Thursday night over the eastern high-lying areas of the Western Cape, spreading to the western high lying areas of the Eastern Cape, the extreme south-eastern high-lying areas of the Northern Cape and the southern high ground of the Free State during Friday morning.
Heavier snowfall of 10 to 20 cm can be expected over the north-eastern high ground of the Eastern Cape, the Drakensberg region of KwaZulu-Natal and the Lesotho mountains from Friday evening into Saturday morning.

Saturday weather forecast
Thunderstorms, combined with strong, gusty surface winds are expected over the central interior by
Friday afternoon, spreading to Gauteng, Mpumalanga and KwaZulu-Natal in the evening and parts of
Limpopo by Saturday.
Due to the pre-existing condition of water-saturated soils in parts of KwaZulu-Natal, rainfall amounts exceeding 20 mm are likely to lead to localised flooding. It is therefore important for communities to take the necessary precautions to prepare for such conditions.
Sunday weather forecast
Rainy conditions are expected to continue over the eastern parts of Limpopo and Mpumalanga and the
northern parts of KwaZulu-Natal during Sunday, however, the public can look forward to a general
clearing of weather conditions as well as a recovery in daytime temperatures from Monday onwards as
the system exits the country.
