UK forecast for the next 5 days

Updated: 14:03 on Sun 23 Jul 2017 BST

Outlook for the UK over the next 6-30 days

UK Outlook for Friday 28 Jul 2017 to Sunday 6 Aug 2017:

After a dry start on Friday, rain will arrive from the west later heralding a rather unsettled spell of weather. Rain will slowly clear on Saturday, turning showery. Heavy showers and strong winds are most likely in the north west, with gales possible in exposed areas. The unsettled regime looks set to continue until early August with further frontal systems affecting the UK, interspersed with clearer or perhaps showery weather and some unseasonably windy conditions across many areas. Temperatures should be around normal to cool, with perhaps only the far south east seeing some warmer conditions at times, although there is low confidence on this. There are no signals for any significant change from these changeable conditions during the period.

UK Outlook for Sunday 6 Aug 2017 to Sunday 20 Aug 2017:

Changeable or unsettled conditions are likely at first with periods of rain interspersed with clearer or showery weather. There are some signals for high pressure to build which would allow for more settled conditions and rising temperatures. By the middle of August signals become mixed and confidence is low, however the preferred solution is for an Atlantic driven setup with the most unsettled conditions in the north west but drier in the south east.
