    Outlook for the UK over the next 6-30 days

    UK Outlook for Monday 31 Jul 2017 to Wednesday 9 Aug 2017:

    A generally unsettled spell of weather is expected on Monday and Tuesday with a mixture of sunshine and showers for most, and possibly a spell of more prolonged rain in the southeast. Heavy showers and strong winds are most likely in the north and west with a risk of hail and thunder, with lighter winds elsewhere. The unsettled pattern looks most likely set to continue until early August with further frontal systems affecting the United Kingdom, interspersed with clearer or perhaps showery weather and some unseasonably windy conditions at times, mainly in the north and west. Temperatures should be around normal to cool, with perhaps only the far south east seeing some warmer and humid conditions at times.

    UK Outlook for Thursday 10 Aug 2017 to Thursday 24 Aug 2017:

    Changeable or unsettled conditions are likely at first with periods of rain interspersed with clearer or showery weather. There are increasing signals for high pressure to build which would allow for more settled conditions and rising temperatures, mostly likely in the south. By the middle of August signals become mixed and confidence is low. However, the preferred solution is for north-western parts to stay largely changeable, with drier and brighter spells of weather becoming more prevalent in the southeast. However, most areas could see showers or longer spells of rain at times.
