UK long range weather forecast
Towards the end of October, Atlantic systems will move in from the west, bringing unsettled and windy conditions. On Friday, although the north and far southeast may see some dry spells, the weather will be unsettled for the rest of the UK, especially in central and western areas, where spells of prolonged heavy rain may develop. The weather will remain unsettled across the UK for the rest of October, with heavy rainfall likely to continue in the west. In the second half of the period, wettest in the west and northwest, but still with brief dry interludes. Driest conditions likely across some south and southeastern areas, with lighter winds and a risk of overnight fog towards the end of the period. Temperatures generally around or slightly above average.
Updated:
In the longer term, a continuation of the generally unsettled theme seems likely at first, with more rain and further showers in many places, especially once again in western areas - with temperatures around or a little above average. Towards the middle and end of November, there are signals for a greater chance of more settled conditions developing, particularly in southern and western areas, where colder nights, with a risk of frosts are likely, as well as an increased chance of mist and fog - especially overnight.
