UK long range weather forecast
Overnight rain and thunderstorms will clear eastwards on Friday, to sunny spells and occasional showers. The showers will mainly be in the west, with a low risk of thunderstorms, and they will introduce fresher conditions. It will be breezy in the north, with further cloud and rain from the southwest later. Into the weekend, confidence falls low, but fresher conditions will be the most probable. A northwest to southeast split will be the most likely scenario. The northwest is likely to see further spells of rain and strong winds at times, with temperatures near or a little below average. The south and southeast are likely to see drier weather, and here it could still be warm into the start of August.
As we move into early August, the final month of the meteorological summer, confidence is low in the forecast with no one single weather pattern looking to dominate. It is most likely that low pressure to the north and northwest of the UK will give further rise to showers or longer spells of rain in the northwest, with the better chance of drier weather in the southeast. Temperatures will likely be above average, perhaps mostly in western and southern areas. However, confidence falls as we head through August.
