Outlook for the UK over the next 6-30 days

UK Outlook for Friday 29 Jul 2016 to Sunday 7 Aug 2016:

Cloud and outbreaks of rain will clear the southeast on Friday to leave cooler and fresher conditions, with sunshine and showers. Showers will be heaviest and most frequent in the northwest and more isolated in the southeast. The remainder of the period is likely to stay rather changeable, with a mixture of cooler and brighter but showery spells and milder and cloudier conditions with outbreaks of rain. Northwestern parts will see the heaviest of the rain along with the strongest winds, whereas the southeast will get the best of the drier and brighter weather. Temperatures should be largely around average, but cooler at times in the northwest and occasionally warm and humid in the southeast.

UK Outlook for Monday 8 Aug 2016 to Monday 22 Aug 2016:

The strongest signal is for the weather across the UK to stay rather changeable throughout this period. There are likely to be warm and settled periods, but also bands of rain, along with spells of sunshine and showers. Most of the rain is likely to be in the north and northwest, with the south and southeast expected to see more of the drier and settled conditions. There is a small chance that a more prolonged spell of warm and settled conditions could develop for a time during mid-August, but confidence in this is current low. Temperatures will probably average out around normal, with some warmer and cooler days likely.
