After an improving day today it's downhill overnight as the cloud rebuilds from the east, it should remain dry, rather muggy once again.
Tomorrow the frontal system that brought heavy rain on Friday returns, various waves of heavier rain will be around during the morning. It's difficult to predict where this rain will be. However, the rain is expected to break and become heavy thundery showers. These could be slow moving leading to localised flooding. A cooler and fresher today tomorrow too.
The next few days sees high pressure trying to increase which should help to settle things down. There will be some showers at times but hopefully some sunshine
