Outlook for the UK over the next 6-30 days

UK Outlook for Monday 21 Aug 2017 to Wednesday 30 Aug 2017:

Rain should sink southeast on Monday, followed by showers in the north and west. Largely settled conditions are likely to develop across the majority of the UK by the middle of next week as showers and rain ease away. A few days of generally settled weather is then expected, barring a few showers. Through the rest of the period, it will probably turn more changeable on the whole with spells of rain, showers and strong winds at times, the heaviest of which are expected in the northwest. However, prolonged drier and brighter periods are likely between these spells of unsettled weather. Temperatures look set to remain around or a little below the average at first, although it may become generally warmer from the middle of next week.

UK Outlook for Thursday 31 Aug 2017 to Thursday 14 Sep 2017:

For the end of August and into the first part of September, we are most likely to see changeable weather conditions dominating across the UK. However, there is a chance of some more prolonged dry and fine weather at times too. As a result, on balance there are likely to be spells of rain and strong winds at times, especially across the north and west, which will then be interspersed with several days of drier and warmer weather. Temperatures may become warm or very warm at times, especially in the south. However, they will probably remain generally close to normal for the time of year elsewhere.
