North West Province
Period: 20 May until 24 May 2019
The cold front that went through the SW Cape and West Coast last night led to widespread falls of 20-40mm. The front will clear these areas this (Monday) morning and will weaken as it pushes into the central interior of the Western Cape and Garden Route. Although it will weaken, these areas are still likely to see 5-10mm of rain during today (Monday).
The rain is not likely to reach the Eastern Cape today, but strong W'ly winds are likely to affect most of the province as well as the Cape S Coast. Areas along the coastal fringe near PE are likely to see winds gusting up to 80km/hr later this afternoon and parts of the central interior will also see gusty NW winds.
Due to the cold front, temperatures today will be cold over southern and western parts of the country. With berg winds ahead of the front, very warm conditions can be expected over eastern parts of the Eastern Cape and KZN. Over the highveld, generally warm condition can be expected with temperatures of around 30ºC forecast for the lowveld.
On Tuesday, the front, along with fresh to strong SW’ly winds will reach the KZN coast. By this point, the front will have weakened however cloudy and cooler conditions can be expected along with the chance of a few light showers for eastern parts of the province. During the day on Tuesday, the cloudy and cooler conditions will also push into the Mpumalanga lowveld with the very warm conditions becoming confined to the Limpopo lowveld.
Elsewhere, Tuesday should be mainly sunny and dry though there is likely to be frost over the southern interior in the morning with maximum temperatures only expected in the teens over southern, central and western parts of the country. Northern parts of the highveld (including Gauteng) will continue to be warm for the time of the year.
On Wednesday and Thursday, temperatures will generally begin to recover by a couple of degrees for most of the country although a morning frost is still likely in places over the southern interior on Wednesday morning and temperatures will cool by a few degrees over the Limpopo lowveld and over northern parts of the highveld. Although a generally dry day is expected countrywide on Wednesday, there is a slight chance of a band of medium level cloud introducing very isolated showers or thunderstorms over southern parts of the highveld and over western areas of KZN.
On Friday and over the weekend, a generally settled period of weather is expected with temperatures continuing to warm over western and southern parts of the country. A cold front may affect the SW Cape late in the day on Sunday, otherwise a dry weekend is expected.
Storms containing large hail: (any mention of thunderstorms in the forecast automatically presumes a very low chance of large hailstorms). Not expected.
Intense lightning: (any mention of thunderstorms in the forecast automatically presumes a low chance of intense lightning).
Flash flooding: (any mention of thunderstorms in the forecast automatically presumes a very low chance of flash flooding). Low chance in the SW Cape on Sunday.
