The very warm or hot weather with extensive sunshine will last through the weekend, albeit on Sunday cloud will build, with risk of bursts of rain, possibly thunder later. The NW Highlands will often be cloudy and until the weekend less hot. Away from the W & NW Highlands, terrain is very dry or exceptionally dry - significant risk of fire. Indications are of it being less hot next week, with rain (including thunderstorms) from time to time within a general area of low pressure that will envelop Britain.
