Heat wave to continue
The current spell of blisteringly hot weather in the South African interior is expected to continue until Sunday.
In the KZN Midlands, temperatures into the 30s will carry on from Wednesday right until Sunday when it will be much cooler, with some rain expected.
The SA Weather Service predicts maximum temperatures of 32, 33 and 32C for Mooi River from Wednesday to Friday, with a minimal amount of rain and a brief thunderstorm at lunchtime on Wednesday. On Saturday it will be around 31C, again with a chance of a few mm of rain.
It’s not much different for Pietermaritzburg, where max temperatures in the provincial capital will range from 32C to 28C until Sunday, when it will drop to a high of just 20C.
In Greytown, Thursday will be the hottest with a sweltering high of 34C, and even Underberg is sweating, with maximum temperatures of 32, 32, 30 and 29 predicted for Wednesday to Saturday.
The Facebook page Storm Report SA, noting the chance of light rainfall in the next few days, says: “On the east coast there is moisture in the air arriving from the east as a strong north-east wind along the northern KZN coast reaches 15 to 25 knots depending on topography (lie of the land). It is this wind that sources the moisture for the light thundershowers expected on the escarpment.”
Regarding the warm, dry conditions gripping the country’s interior, it states: “High temperatures aside, this pressure pattern is very typical of winter, when the overland High “HD” becomes firmly established and ensures calm, sunny conditions for all our forecast areas except the southern Cape. It is the main cause of the warm, dry, cloudless days, and its divergent wind system usually blocks incoming moisture and cold fronts. Well, here we see it in summer, blocking incoming moisture and trapping the air inside to become heated by a fierce summer sun only 5 weeks away from mid summer’s day.”
