UK long range weather forecast
The start of the period remains unsettled with strong winds and frequent outbreaks of rain across much of the country, particularly in the north and west. This will likely fall as snow over high ground and may also at times fall to lower levels too, especially over northern and eastern areas. Further into this period unsettled conditions look most likely with low pressure dominant across the UK, bringing changeable weather with periods of rain, showers, and strong winds. Northerly winds are expected at times, increasing the risk of snowfall especially in the north. In the south, milder interludes may occur bringing at or above average temperatures. Overall temperatures are likely to be rather cold in the north but close to average in the south.
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.
