Forecaster Kumsa Masizana said relief from the heatwave was well on its way as it was expected to have left the eastern parts of the Northern Cape, parts of the Free State and North West by yesterday, reports The Citizen.

However, she said it would only completely dissipate from the other parts of the country – particularly the northeastern provinces – today as a cold front was expected to come into the country and make landfall.

She added that the cold front would only touch the southern provinces before making its exit from the country, leaving behind cool air.

As a result of the cold front, she said: “There will be a 30%-60% chance of rain over the central and eastern parts of the country and an 80% chance in southern eastern parts including the eastern parts of the Eastern Cape and KwaZulu-Natal”.

She warned that there could be severe thunderstorms and localised flooding while the rest of the country would have cooler temperatures.

She said the cooling temperature would go on for the rest of the week until Friday, with a 30% to 60% chance of isolated to scattered thunder showers expected in the central and eastern parts of the country.

According to weather website ventusky.com, the temperature in Gauteng could dip to as low as 13°C at 2pm on Wednesday.
