Outlook for the UK over the next 6-30 days

UK Outlook for Friday 20 Jul 2018 to Sunday 29 Jul 2018:

After a mostly dry and bright start, cloud and outbreaks of rain are possible across northwestern parts on Friday. Central and southeastern areas will be very warm again, but cloud will tend to increase during the day and a mixture of showers or longer spells of rain may develop, perhaps heavy and thundery across the southeast. By Saturday any rain in the north will probably be replaced by sunshine and showers, while further south, warm sunshine is likely. Dry, fine and warm weather will predominate in the south throughout the following week, though occasional showers remain possible, perhaps including thunder and lightning. It will be more changeable and breezy further north with outbreaks of rain or showers at times, but there will also be some drier, warmer and sunny spells.

UK Outlook for Monday 30 Jul 2018 to Monday 13 Aug 2018:

There are limited indications of the weather expected in August. In general, southeastern parts are more likely to have dry and warm or very warm weather, though showers are likely at times, and perhaps some thundery episodes. Further northwest, fine weather will probably last for shorter periods and changeable breezier weather may dominate, though even here temperatures are likely to be warmer than the August average.
