A northwesterly airflow is likely to affect the UK and Ireland on Tuesday bringing cold temperatures to northern and western areas. Icy patches are likely in the north and west while a widespread frost will affect most areas in the morning. Showers, with a mix of rain, snow and sleet for western coastal areas and across the West Midlands. Sunny spells further inland and across the southeast. High temperatures at 0 to 5C.
A west to northwesterly flow persists. A very cold start to the day with a widespread hard frost and ice patches. A few wintry showers for northern and western areas with the risk of a frontal system moving in across central-southern Britain later in the day, producing a more persistent mix of rain and snow. Highs at 0 to 6C, locally higher in the far south and southwest.
A low pressure area may track over southern Britain which would bring a disruptive mixture of high winds and persistent snow to northern areas; high winds and persistent rain to southern areas. Detail is highly uncertain at this lead time. Highs at 0 to 4C in the north, 6 to 10C in the south.
A northwesterly flow may re-establish bringing cool temperatures and unsettled weather. An ongoing risk of high winds and wintry showers. High temperatures at 4 to 7C.
Low pressure remains close by bringing chilly and unsettled conditions. If low pressure moves to the east it could be a brighter day for many with some scattered wintry showers. Detail remains uncertain. Highs at 2 to 7C.
Early indications are that low pressure will remain dominant on Sunday with a risk of a more persistent, organised band of rain and snow affecting the UK and Ireland. Detail continues to be highly uncertain. Highs at 3 to 7C.
