UK long range weather forecast
From Thursday onwards, rather cold and unsettled conditions look likely for most of the UK, as a low pressure system remains to the northeast. Northwesterly winds from this system are expected to bring frequent showers, particularly to north and west-facing coasts, and this will likely fall as snow over high level areas, and also down to lower levels at times. Atlantic low-pressure systems are expected to cross the south of the country at times, bringing rainfall and periods of slightly milder temperatures, and there will be a risk of snowfall on the boundary between the mild and cold air masses. Northern and central areas are more likely to be affected by wintry hazards during this period.
Updated:
Confidence for this period is low, though there is a signal for weaker than average westerly winds and for Atlantic low-pressure systems to track further south than normal. This will bring below-average temperatures to the north of the UK, with a greater than normal risk of wintry precipitation. Further south, there is a continued risk of unsettled conditions, with above-average rainfall and periods of slightly above average temperatures. There remains the potential for significant snowfall along the boundary between colder air to the north, and the milder air in the south, with the greatest risk across central and northern areas. Through this period there is a greater than average chance of cold spells spreading across the whole UK at times with the associated risk of wintry hazards.
