UK long range weather forecast
Unsettled conditions look likely to dominate for this period, with low pressure across the UK. This should bringing changeable weather to most of the country, with periods of rain, showers, and strong winds at times. While westerly and southwesterly winds are expected to be dominant for most of the period, occasional northerly winds are possible, brining a chance of snowfall, likely confined to the far north. Milder conditions in generally may start to spread across most of the UK at points during most of this period. Towards the end of the period, we may see high pressure bringing a higher than average chance of cold weather with wintry outbreaks. However, there is a chance of drier than average conditions, which would bring increased frost and fog risks.
Updated:
Confidence for this period is low, though low pressure is likely to be dominant at first with an increased chance of northerly winds. This will therefore increase the risk of snowfall especially in the north along with colder than average temperatures, potentially bringing wintry hazards more widely. Through mid-February higher pressure may develop for a time which would bring drier conditions with an increased likelihood of fog and cold, frosty nights.
