Africa: Africa Weather Forecast launched their climate summary in which they reported strong winds, intense rainfall and possible hail in the east this weekend as a well-developed Cut-Off Low ravages the central and eastern regions. Otherwise, very light showers are expected in the east at first but fine and warm to hot elsewhere.
Minor upper air perturbation following close behind the recent system is expected to seed isolated thunderstorms along the eastern escarpment and rainfall along the south coast on Tuesday and Wednesday, with the next round of showers and thundershowers expected over the central interior on Friday and the weekend.
Driven by an upper air low, this weekend system promises thunderstorms, strong winds, heavy rainfall, and large amounts of small hail over the central and south-eastern regions.
MONDAY: Mostly dry and warm but hot in the north. Otherwise, partly cloudy in the east and south with a low chance of afternoon thunderstorms along the eastern escarpment and a medium chance of strong westerly winds over the southern Northern Cape in the second half of the day.
TUESDAY AND WEDNESDAY: Partly cloudy in the southwest in the morning, with a high chance of light morning rainfall along the south coast, followed by showers and thundershowers scattered along the eastern escarpment (KwaZulu-Natal, eastern Eastern Cape and eastern Mpumalanga) on Tuesday afternoon and evening, and in some places in the east, persisting into Wednesday morning where it mixes with fog patches over the far north-eastern escarpment on Wednesday.
Low-level wind shear from a low-to-mid-level inversion over KwaZulu-Natal midlands and northern regions up to southern Mpumalanga leads to a low chance of high-impact thunderstorms on Tuesday.
THURSDAY AND FRIDAY: Thursday seems to be mainly dry as partly cloudy skies will be confined to the far east, where there is a medium chance of light rainfall and isolated thunderstorms (eastern Free State, KwaZulu-Natal, southern Gauteng, eastern North West and western Mpumalanga).
Otherwise, Friday has a better chance of showers and thundershowers, scattered over more central parts and eastern escarpment but isolated in the far east, where lighter rainfall is anticipated.
The weekend: Saturday will be partly cloudy at first, with very isolated morning thunderstorms in places over the central interior, but becoming cloudier with a high chance of scattered showers and thundershowers as a band of tropical moisture connects to the southern tip of the continent.
In some places over the central interior, these showers will last until Sunday, when they become more intense, precipitating moderate-to-heavy rainfall in the southeast.
