UK heatwave: Will tomorrow evening's solar eclipse be visible where you live? Scotland and Northern Ireland will see more cloud and occasional rain, with some heavier or even thundery bursts possible at times. Northern Scotland will remain cloudier with outbreaks of rain, while Northern Ireland may also see the odd spot of rain. Temperatures are expected to climb to 33°C or 34°C in the south, while many northern areas could reach the mid or even high 20s. Further east and south across Scotland and Northern Ireland, there is a better chance of cloud breaks.
