Things set to clear for Mother’s Day weekend

Despite the unsettled end to the week, conditions are forecast to improve over the weekend with fine and mild weather expected across most of the country.

MetService forecaster Mmathapelo Makgabutlane said this bad weather is “looking fairly relatively short-lived, so by Saturday morning all this weather looks like it’s cleared off the country and the weekend is looking pretty good”.

MetService said Mother’s Day is shaping up to be settled and sunny for most, though some regions may experience morning cloud or fog.
