Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 8 Aug 2015 to Monday 17 Aug 2015:

Any showers in the east on Saturday should die out with most parts then fine, although showers may occur in the south. Unsettled conditions are likely to push into the west on Sunday morning, then extending to central parts. The southeast staying mainly dry although thundery showers may occur here later. Through the rest of the period, westerly or south-westerly winds will push bands of rain or showers across the country at times, interspersed by some drier and brighter interludes. The wettest and windiest weather occurring in the north and west, with the south seeing the best of the brighter weather. Temperatures will range from rather cool in the northwest, to near normal in the east, although there is the chance of some brief very warm interludes in the southeast.

UK Outlook for Tuesday 18 Aug 2015 to Tuesday 1 Sep 2015:

The changeable 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 thundery 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, particularly in the southeast.
