Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 1 Aug 2017 to Thursday 10 Aug 2017:

Remaining unsettled with sunny spells and showers through Tuesday. The heaviest and most frequent showers affecting the north and west, with much of the south staying largely dry, with sunny spells. We are likely to see a low pressure system push in from the Atlantic on Wednesday, bringing a spell of wet and windy weather to some western parts of the United Kingdom, spreading to all parts on Thursday. Thereafter, we are likely to see a return to sunshine and showers, most frequent and heaviest in the northwest. Into the weekend and early next week, we may begin to see conditions becoming more settled across the UK, with high pressure building from the southwest, with a predominately north-westerly flow. Temperatures will generally be around normal to rather cool throughout.

UK Outlook for Friday 11 Aug 2017 to Friday 25 Aug 2017:

There are increasing signals for high pressure to build during this period, which would allow for more settled conditions across the United Kingdom, with a predominately west to north-westerly flow becoming established. However, there will still be the risk of spells of rain or showers, mainly in the north, but overall a good deal of dry weather with some sunshine, especially in the south. Temperatures generally near normal by day, but potentially rather cool at night. By the middle of August signals become mixed, with low confidence. On balance though, we are most likely to see a northwest/southeast split in weather conditions across the United Kingdom, with some rain or showers in the northwest and drier conditions with some sunshine in the southeast.
