UK long range weather forecast
Unsettled conditions are expected to dominate for the rest of October, with showers or longer spells of rain interspersed with occasional sunny spells. Strong winds are also likely with gales possible at times. The wettest, windiest weather is most likely in the north and west of the UK whilst the best of any drier or brighter weather across the south and east. It will become milder however. A change to generally drier, more settled conditions is expected for the start of November with any strong winds, showers or longer spells of rain most likely confined to northern areas. Elsewhere winds will probably become mainly light. These more settled conditions bring an increased risk of colder weather with overnight frost and morning fog, particularly across the south.
Updated:
For the remainder of November, it is likely to be a tale of 2 halves. The start of this period looks set to see high pressure dominate, bringing more settled conditions than seen in recent times, particularly for the south with any wet and windy weather most likely to affect the north-west. Although confidence lowers toward the end of November, a return to unsettled autumnal weather is most likely, with showers or longer spells of rain and strong winds, interspersed with drier intervals. Overall, temperatures are anticipated to be at or below average for this time of year.
