UK forecast for the next 5 days

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

Sunny spells and showers or rain for many, turning heavy and perhaps thundery at times, especially over Scotland. Largely dry in the southeast with warm sunny spells, but isolated showers possible towards the end of the day.

Showers continuing to affect the north overnight, but easing and becoming more isolated through the evening across the south, with clear spells developing. Winds will be mainly light.

Showers in the north and west, occasionally heavy and possibly thundery, will spread into more central areas through the day. Southeastern parts will stay largely dry and warm though.

Issued at: 0500 on Thu 31 Jul 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Monday 4 Aug 2014 to Wednesday 13 Aug 2014:

Many areas probably starting off fine and generally dry on Monday. However, cloud and rain, possibly heavy at times, will gradually spread from the west through the latter part of Monday, through probably not reaching eastern regions until later on Tuesday. The unsettled theme is likely to continue until the end of the period, although there may be more in the way of drier and brighter conditions developing across the south and east later. 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, with a risk of gales in some exposed western parts into the second half of next week.

UK Outlook for Thursday 14 Aug 2014 to Thursday 28 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 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.
