UK Outlook for Tuesday 22 Aug 2017 to Thursday 31 Aug 2017:

An unsettled start with showers or longer spells of rain are likely to affect the north on Tuesday with strong winds. Sunshine and showers are expected elsewhere. Drier and brighter conditions will probably spread to other areas on Wednesday and winds will ease. Through the rest of next week, it is likely to be rather changeable in the north with spells of rain. Places further south will see more prolonged drier, brighter and warmer conditions. For the rest of the period, it is most likely that many areas will see spells of cloud and rain at times, interspersed with a few days of brighter, showery conditions. Temperatures look set to be around average for the time of year, although it could turn warm in the south at times.

UK Outlook for Friday 1 Sep 2017 to Friday 15 Sep 2017:

As we head into 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, probably interspersed with several days of brighter and showery 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.
