Outlook for the UK over the next 6-30 days

UK Outlook for Thursday 6 Aug 2015 to Saturday 15 Aug 2015:

Unsettled and often wet conditions are expected to persist in the north on Thursday with southeastern parts having the greatest chance of staying dry with some sunshine, although there is a risk of some thundery showers here later in the day. Generally drier and brighter on Friday, particularly in the southeast. Conditions will then remain generally unsettled with bands of rain, accompanied by strong winds, pushing in from the west at times. These will be interspersed with more showery conditions with the southeast seeing the best of any drier weather. Temperatures are likely to range from rather cool in the north and west to nearer normal in the south and east, although some transient warm spells are possible in the southeast at times.

UK Outlook for Sunday 16 Aug 2015 to Sunday 30 Aug 2015:

The unsettled theme is likely to continue for much of the UK to the end of August with wet and windy conditions at times, particularly in the north and west of the UK. Southern and eastern parts will continue to see the best of any drier and brighter spells, although there is still a risk of rain or showers here at times. There is a weak signal for some periods of drier and more settled weather to develop towards the end of the month, however confidence in this is currently low. Temperatures on the whole will be near or below average for the time of year, especially in the north, although during any more settled spells of weather it could turn warmer at times in the southeast.
