UK long range weather forecast
A mixture of sunny spells and showers, with some drier interludes is the general pattern expected through the start of this period, as unsettled, changeable conditions continue to dominate. Some of these showery spells may merge to give slightly longer spells of rain, with some thunderstorms likely to develop from these. Torrential downpours are likely in some places. There is a risk of strong winds at times for some, and temperatures are expected to be below average, but perhaps slightly above average in northern areas. Through the remainder of this period, it will likely turn more settled, though a few showers cannot be ruled out, especially in southeastern areas. This will bring drier weather, with sunny spells for most through to mid-August, and temperatures trending closer to, perhaps above average.
Updated:
Whilst there are current signals of a drier and warmer than average period from the middle of August, occasional spells of more unsettled weather, primarily in the northwest, remains possible. Accompanying this is a low risk of short-lived thundery spells, these mainly in southeastern parts. Confidence through this period remains low at present. However, most should see dry and fine weather. Above average temperatures continue to be indicated through the second half of August, with a small possibility of very warm conditions at times in southern areas.
