UK long range weather forecast
Changeable conditions continuing to dominate for the start of August, with a mixture of sunny and dry periods, showery periods and the chance of longer spells of rain. At first the south is likely to see the most showers, with the north remaining the driest, but by the end of the period the south and southeast will possibly be the driest and the west and northwest the wettest. There remains a chance for any showers or rain to produce thunderstorms. 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:
As is typical for this time of year, confidence is low for this period. However, 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.
