Saturday should see a fair amount of settled and sunny weather as a ridge of high pressure builds across the south of the UK, with scattered showers becoming mostly confined to Scotland and Northern Ireland. High pressure will give way to another Atlantic low pressure through Sunday and into the following week bringing changeable weather with bands of rain crossing most areas at times, but more especially affecting northern and western parts. Towards the south and southeast it will most likely stay drier, and possibly become warm at times, but there is the risk of some thundery showers spreading in from the south. There are signs that high pressure may become more dominant by late-June, bringing a chance of settled and warm weather. Temperatures mostly near normal.

Although uncertain, the most likely weather for the start of July is for a continuation of the mostly dry and warm weather in the southeast of the UK, with generally light winds. However the risk of some thundery outbreaks remains. Windier and wetter weather is likely at times in the northwest but there will be drier spells here too. Temperatures will be near or slightly above the average for the time of year.
