Outlook for the UK over the next 6-30 days

UK Outlook for Friday 1 Aug 2014 to Sunday 10 Aug 2014:

Southern and eastern parts of the UK are likely to start largely dry and fine, although outbreaks of rain or showers in the west will spread to most parts through Friday. Over the weekend and into the following week, it is likely to remain unsettled across the UK with further outbreaks of showers and more prolonged rain affecting all areas at times. Rain is likely to turn occasionally heavy, particularly towards the middle of the week. Temperatures should be around normal for the time of year, and perhaps on the warm side in the south. There are indications that drier, sunnier periods may become more prevalent in southern, eastern and central areas later in the period as bouts of rain are likely to become more confined to the northwest.

UK Outlook for Monday 11 Aug 2014 to Monday 25 Aug 2014:

With no particularly strong signals regarding weather patterns over the UK during mid-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.
