UK long range weather forecast

A low pressure system to the north of the UK will dominate during the start of this period, bringing heavy rain and isolated thunderstorms for all. Thereafter, further low pressure systems will affect the UK, particularly northwestern areas. This will bring organised bands of rain, heavy at times, interspersed with cooler and showery periods but some sunny spells too. Drier and more settled conditions are likely across southern and eastern parts of the country, but there is still a chance that bands of rain and strong winds from the north and west could extend into these areas. The temperatures are most likely to be slightly below average for this time of the year during the start of the period, but will gradually return to near average later.


Confidence is typically low during this period, but the most likely outcome is for high pressure to dominate in the south, leading to drier and more settled conditions over these areas. In the north, lower pressure is likely to prevail, with these areas seeing the wettest weather. However, there is a chance of settled conditions becoming more prevalent across most of the UK for a time. Temperatures are more likely to be around or slightly above average.
