UK forecast for the next 5 days

Sunny spells and showers, locally heavy. Drier towards the southeast.

This Evening and Tonight:

Showers will continue to affect the northern and western areas overnight, but easing and becoming mainly dry elsewhere, with clear spells developing. Winds will also be mainly light, possibly allowing some localised mist patches to form, particularly in the south.

Friday:

Showers and brighter spells for many areas, showers merging into longer spells of rain for parts of Wales and southwest England later. Southeastern England will stay largely dry and warm.

Issued at: 1700 on Thu 31 Jul 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 5 Aug 2014 to Thursday 14 Aug 2014:

Rain, heavy at times, is likely over western parts early Tuesday, slowly moving east and easing through the day. Further rain is likely in the west on Wednesday, also moving east and easing, but brining strengthening winds to all parts. Remaining predominantly unsettled into the weekend, wettest in the northwest but with a low risk of thundery showers in the south and east at times. Conditions then most likely to become more settled in the south until the end of the period, with more in the way of drier and brighter conditions developing across the south and east. Temperatures generally near normal, but often warm towards the south and east. Winds generally light to moderate for most, but perhaps locally strong in the northwest at times.

UK Outlook for Friday 15 Aug 2014 to Friday 29 Aug 2014:

With no particularly strong signals regarding weather patterns over the UK during the latter part of August, conditions are more likely than not to be close to climatology. As such most regions can expect to see periods of fine weather with some sunshine interspersed by occasional spells of more changeable conditions with showers or rain. Northern and western parts are perhaps most likely to see the most frequent bouts of unsettled weather leaving southern parts with the most prolonged fine spells. Daytime temperatures are then likely to often be above average during fine spells.
