A windy and wet day across northern Scotland with outbreaks of rain and a few showers may affect parts of Northern Ireland.

Most parts of the United Kingdom will have another very warm to hot day with any early mist or low cloud soon breaking to sunny skies. Perhaps the odd shower may develop across the Pennines in the afternoon. It will be fine and dry to the evening with sunny spells and dry overnight with clear intervals but more cloud may affect Scotland and parts of northern England. Maximum temperatures of 22 to 29 Celsius.
