UK long range weather forecast
Changeable conditions continuing to dominate the first half of August, with a mixture of sunny and dry periods and showery spells for all, possibly merging to give longer spells of rain. Widespread thundery showers will give away to bands of rain from the Atlantic which may bring unsettled conditions to all parts. However the south and southeast potentially seeing drier weather and the west and northwest the wettest. There remains a chance for any showers or rain to produce thunderstorms, particularly in the far south. Temperatures are most likely cooler than average for this time of year, trending to slightly cooler than average or average through the period, with the south and southwest having the best chance of seeing average temperatures.
Updated:
There is a tentative sign of more settled conditions developing with higher pressure becoming slightly more likely. This means drier conditions may become more prevalent, although there is still the risk of showers or thunderstorms at times. Temperatures likely to trend to above average, with an increasing chance of hotter spells developing as the month progresses.
