UK long range weather forecast
The unsettled, changeable conditions continue to dominate the picture for the first half of August. A mixture of sunny spells and showers, with some drier interludes, is the general pattern expected through this period for all. Some of these showery spells may merge to give slightly longer spells of rain. At first, scattered showers for most, with some thunderstorms likely to develop from these. Torrential downpours are likely in some places. Winds generally remaining breezy, with temperatures expected to be near to average, perhaps slightly above average in northern areas. Through the remainder of this period, it will likely turn settled, though a few showers cannot be ruled out, especially in southeastern areas. Drier weather than recently, with sunny spells for most through to mid-August, with temperatures trending 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. Most should see dry and fine weather, however. Above average temperatures continue to be indicated through the remainder of August, with possibly even very warm conditions at times in southern areas.
