Outlook for the UK over the next 6-30 days

UK Outlook for Thursday 27 Jul 2017 to Saturday 5 Aug 2017:

Some rather unsettled weather looks set to affect the UK with often cloudy conditions with heavy rain moving across the country at times. A mixture of sunny spells and showers between the heavier spells of rain looks likely. Temperatures will be cooler generally, especially in any rain or showers but some warmer spells also. The unsettled or changeable theme looks likely to remain through the end of July, with north-western areas seeing the heaviest rain and showers and stronger winds. South-eastern areas are likely to be drier through the period, however a more prolonged spell of settled weather looks unlikely at this point. Signals in early August look very weak however there is increasing confidence for a continuation of changeable weather influenced by the Atlantic.

UK Outlook for Sunday 6 Aug 2017 to Sunday 20 Aug 2017:

Despite rather mixed or weak signals for this period, the most likely scenario is for a changeable Atlantic driven airflow across the UK. This is likely to bring showers or longer spells of rain, and chance of strong winds at times. Southern and eastern areas are most likely to see periods of more settled weather. Temperatures may also recover to some extent through August, particularly in the south, to average or perhaps above.
