Tuesday:

Mainly cloudy with outbreaks of rain and drizzle through the morning, heavy over higher ground at first. Brightening up through the afternoon. Severe gales easing but staying windy. Exceptionally mild. Maximum temperature 16 °C.

Drier and brighter on Wednesday with sunny periods and isolated showers. Probably dry with bright spells on Thursday. Rain likely at times on Friday. Often rather windy. Staying very mild.

A continuation of a similar pattern to that seen through early December is anticipated, especially at first, as frontal systems from the Atlantic spread into and across the UK, interspersed with some temporary drier interludes. These will bring spells of rain, which may be heavy at times leading to the risk of some impacts given how wet it has been lately, especially in the west. In addition, there may also be potential for some periods of strong winds at times too. Whilst it will often be mild, later in the period there may be a slight downward trend in temperature, especially across northern parts of the UK where there may also be a slightly higher chance of some wintry hazards at times.

Changeable conditions are expected across the UK during this period. Low pressure systems will probably dominate, meaning showers or longer spells of rain, heavy at times, for much of the UK and some hill snow in the north. Periods of strong wind are also possible, especially around coasts. Some drier, more settled spells are possible but how long these last is very uncertain. Temperatures will likely be close to average or slightly above overall.
