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, potentially becoming heavy in places. There is also a chance that there could be some further thundery weather, although this would most likely be confined towards the east and southeast of the UK. It is likely to be windier than of late, especially in the south and 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 with freshening winds from the northwest likely to create a more widespread risk of gales.
Updated:
Although confidence is low for this period, it is likely that conditions will become more changeable with drier and brighter days interspersed with periods of rain and strengthening winds. Temperatures should be around the average for this time of year. Towards the end of this period, there are some tentative signs that high pressure could begin to dominate, especially across the south of the UK, with a return to more settled conditions.
