Outlook for Sunday to Tuesday:

Dry at first on Sunday but then patchy rain spreading east during afternoon and evening. Mainly dry early next week, just the odd shower in the north.

A transition to a rather more changeable and at times unsettled weather pattern is likely to occur during the first few days of this period. Outbreaks of rain and freshening winds will probably make inroads from the southwest during Thursday ahead of conditions more widely becoming wetter and windier by next weekend. Whilst a milder, wetter and windier scenario is considered most likely, there remains a small chance that colder air from Europe may continue to feed into northern Britain, especially at first, increasing the chance of snowfall here. Towards the end of January, further periods of strong winds and heavy rain are likely to move in from the Atlantic. Whilst generally mild conditions look to close out the month, some large day to day changes in temperature are possible.

A dominant flow from the Atlantic looks likely through this period, resulting in an unsettled, milder and windier than average period. This is likely to result in areas of rain and periods of stronger winds affecting most if not all parts of the UK at times, though with the wettest and windiest weather probably occurring towards the north and west. However, the potential for brief colder spells with associated frost, ice and snow remains, following any deep lows crossing the region. Pressure may build across southern areas towards mid-February, which would result in drier, settled conditions, albeit with an increased chance of overnight fog and frost, becoming established here.
