There might a yellow thunderstorm warning for the whole of Wales in place for some of the weekend, but at the same time temperatures are set to rise. Parts of Wales could see highs of 29°C over the weekend, making it warmer than Barcelona, Corfu and Istanbul.
A plume of warm air is set to raise temperatures but increase the risk of thundery showers at the same time.
The high pressure area which has been responsible for the settled weather for much of the UK will drift away towards Scandinavia, allowing a plume of warm air from the south to influence the weekend weather for much of the UK. Welsh weather forecaster Derek Brockway says it hasn't rained in parts of Wales since May 8.
