CAPE TOWN - On Wednesday night a cold front made landfall over the south-western Cape and brought much needed rainfall to the region.
As the cold front moves eastwards during the course of Thursday, weather clears over the western parts, but deteriorates in the east where a chilly, autumn weekend is likely.
As the cold front moves eastwards on Thursday strong, to gale force winds are likely between Cape Agulhas and Port Elizabeth, while it will stay mostly cloudy and cold in the Western and Northern Cape.
The cold front is accompanied by a sharp upper air trough. The passage of this trough will be characterised by thunderstorms over the central parts, and later on the Highveld and interior of KwaZulu Natal.
Good Friday will be characterised by cloudy and showery conditions over the eastern parts of South Africa together with much cooler conditions in the Eastern Cape, Gauteng, KZN and Mpumalanga.
A very wet day is expected in Limpopo and Mpumalanga as the passing upper air trough provides a favourable environment for the development of thunderstorms.
Meanwhile, the Easter long weekend will have a very chilly start over the interior of the Cape Provinces and minimum temperatures could drop to below 5ºC in parts of the Karoo on Friday morning.
A sunny but windy day awaits Cape Town, while light rain will start clearing along the Western Cape south coast. Light rain remains in the forecast for the coastal areas of the Eastern Cape.
Another cloudy and wet day awaits the northeastern parts on Saturday and a ridging high pressure system will result in further cooling.
But as it gets colder in the east, the Cape Provinces can look forward to a significantly warmer day and near perfect conditions for runners of the Old Mutual Two Oceans Marathon in Cape Town.
It becomes even warmer in the west on Sunday when Cape Town could reach a high of 30°C. The eastern parts of South Africa will still experience chilly autumn weather and light rain remains possible.
