UK Outlook for Thursday 8 Sep 2016 to Thursday 22 Sep 2016:

There is some doubt in the detail of the forecast for this period, but the most likely scenario is for westerly or southwesterly winds to dominate. This will bring changeable weather, with showers or longer spells of rain interspersed by some dry and bright periods. The heaviest and most persistent rain is expected to occur in the north and west, where it could also be windy at times. The best of the brighter weather probably occurring in the south and east. A trend towards drier and more settled conditions looks more possible during the second half of September. Temperatures through this period are likely to be generally above average, with any colder spells being transient.
