Outlook for Tuesday to Thursday:
Rain arrives westward Tuesday morning, turning locally heavy. Drier Wednesday, before further rain arrives in the evening. Some showers remain Thursday morning, but soon clear to give a dry day.

UK long range weather forecast
Unsettled conditions look likely to dominate for this period, with low pressure across the UK. Therefore, this should bring changeable weather to most of the country, with periods of rain, showers, and strong winds at times. While mild westerly and southwesterly winds are expected to be dominant for most of the period, occasional colder northerly winds are possible, bringing a chance of snowfall, likely confined to the far northern parts. Towards the end of the period, we may see high pressure bringing a higher than average chance of cold weather more widely with wintry outbreaks. If this were to occur many inland and southern areas would likely see drier than average conditions, with some overnight of frost and fog.
Updated:
Confidence is low for this period, but current signals indicate a possible high pressure system around or near the UK during this period. This would likely bring cold northerly winds, producing colder than average temperatures and wintry outbreaks. The second half of February is likely to have a mixture of weather types, with periods of wet, windy and milder weather interspersed with drier, calmer, colder periods.
