Regional Forecast for Wales

Tonight:

Tonight will be dry with clear spells, however low cloud will develop over higher ground giving some patches of hill fog. Minimum temperature 11 °C.

Tuesday:

Tuesday will see another fine day with sunny spells and light winds, with just the small chance of an isolated shower. In the sunshine it will feel warm. Maximum temperature 22 °C.

Outlook for Wednesday to Friday:

Updated: 01:14 on Mon 24 Jul 2017 BST

UK forecast for the next 5 days

Headline:

Fine for many, cloudy and damp in the east.

Today:

Fine and warm for most western parts with plenty of sunshine, although the chance of the odd shower in central Scotland later. Cloudier and cooler on coasts in the north and east with rain across eastern England, slowly easing.

Tonight:

Sporadic rain will continue across East Anglia and southeast England before eventually fading by dawn. Elsewhere, dry with clear spells but staying cloudy on coasts in the north and east.

Tuesday:

Cloudy and damp in the east at first, but soon turning drier and brighter with plenty of sunny spells across the UK. Perhaps the odd shower later. Generally warm.

Outlook for Wednesday to Friday:

Changeable and often windy with a spell of rain for all during Wednesday. Drier in the south on Thursday and Friday, but blustery showers elsewhere, heavy in the northwest.

Updated: 01:14 on Mon 24 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.
