Why is the sky blue?

UK long range weather forecast
It will be unsettled this coming weekend, with rain clearing the northeast on Saturday. The rain will be followed by sunny spells and scattered, heavy showers, with the risk of thunderstorms. Temperatures will be near the seasonal average, but it will be warm in the south and east. While there will be a few showers in the northeast on Sunday, many areas will be drier, with sunny spells. Into the following week, conditions will probably stay changeable and breezy at times, with showers or longer spells of rain but also some brighter and drier spells. It may become generally drier and brighter, more especially in the south and southeast, with the more changeable conditions persisting across northwestern parts of the UK.
Updated:
The forecast is very uncertain at this stage, with mixed signals for higher or lower pressure by the end of July. However, there are signs of a possible more settled and drier interlude for many. Into August, there are very weak signs of some rain, possibly thundery outbreaks, developing across parts of the UK. Temperatures are likely to be above the average overall, especially in the south and east, where it will possibly be rather warm and humid at times.
