Tuesday begins on a cloudy note across central and southern Britain, with occasional rain and drizzle. However, conditions are expected to improve as the day progresses, with the cloud clearing from the north and rain becoming confined to southern counties. Inland areas will see the low cloud

While some areas will start off cloudy, particularly in the east, conditions are expected to improve as the days progress, offering ideal weather for outdoor events and activities. Saturday will begin with widespread cloud cover across Scotland, England, and eastern Wales, accompanied by hill fog

On Monday, cloud dominates the morning across northern and northeastern areas, bringing patches of drizzle. A central band of the country could see isolated showers, but as the day progresses, cloud cover breaks to reveal sunny spells. These brighter conditions are short-lived in some areas

temperatures are expected to reach between 27°C and 29°C quite widely, with some locations in southern England potentially peaking at 30°C or 31°C. Further north, conditions will remain largely dry and warm, although there will be more cloud, particularly along North Sea coasts. A few isolated showers

It is likely that significant amounts of cloud will be trapped under the ridge and this could be thick enough to generate
