Tue 26 Aug Wales

The forecast for Bank Holiday Monday is for reasonably fair weather, with light winds and sunny spells continuing from the weekend. However there is still a small chance that western or southwestern parts could see some cloudier skies and a few showers. As the week goes on, skies may become generally cloudier, and there is an increasing chance of outbreaks of rain and showers. Any precipitation would be initially across the southwestern half of the UK, and possibly spreading further north and east at times. That being said, fair conditions are still possible between weather systems. Winds could be breezy at times too, especially around exposed coasts and some hills. Temperatures will be around normal, perhaps a little above in places where sunnier spells persist with lighter winds.
