UK long range weather forecast
The beginning of this period is likely to be generally unsettled, with showers and longer spells of rain at times. There is also a low chance that there could be some further thundery weather, although this would most likely be confined towards the southeast of the UK. It is likely to be windier than of late, especially in the west where there is also a risk of gales. Temperatures should start rather warm for many, despite the spells of unsettled weather. However, temperatures may cool slightly by the end of this period as the low pressure system, which was situated over the west of the UK, pushes towards the east and allows for a freshening breeze to develop from the northwest.
Updated:
Although confidence is low for this period, it is likely that conditions will become more changeable with settled days interspersed with periods of rain and strengthening winds, especially in the northwest. However, the east and southeast will perhaps remain slightly more settled throughout with temperatures around or above average. There is also a possibility for southern regions to turn very warm at times, with a potential for thunderstorms to develop.
