Tuesday: A few showers are likely but much of the UK has a dry, sunny and warm day. However, in the north west cloud thickens and outbreaks of rain develop.

Outlook: Rather changeable conditions are likely to return. Therefore, the chance of wet spells increases, and Wednesday could bring a period of heavy rain to much of the UK. However, rainfall amounts in the south probably remain small. Temperatures dip back towards the late September average.
