Cloudy with outbreaks of rain for all areas during the evening, then becoming dry and chilly after midnight with clear spells developing, allowing a patchy frost and areas of mist to form by dawn. Minimum Temperature 1C.

Monday:

A dry, bright, chilly start, with mist soon clearing to leave a dry day with mild sunny spells, though turning cloudier and breezier through the afternoon, with rain arriving later. Maximum Temperature 11C.

Outlook for Tuesday to Thursday:

Tuesday cloudy and windy with outbreaks of rain, but milder than recent days. Wednesday brighter, colder and less windy, with occasional heavy showers. Thursday, bright and breezy with isolated showers.

Day 6 to 15

Friday starts dry for most with patchy frost and fog, but cloud and rain already in the southwest will spread northeastwards through the day. Clearer, windy and showery conditions follow from the southwest later, these lasting into Saturday. Unsettled weather is likely to continue into the Christmas period, with further spells of rain possibly preceded by hill snow, and with strong winds at times. However during the last week of December there is a chance that the weather pattern will become slow-moving, with some more settled drier conditions developing, and with any rain increasingly confined to the north and west. Temperatures are likely to fluctuate around average, but turning colder should more settled conditions develop.

Day 16 to 30

Going into the New Year there is an increasing likelihood of the weather pattern becoming slow-moving or even "blocked", with Atlantic frontal systems held at bay by slow-moving areas of high pressure. This may result in more generally settled and cold weather conditions becoming established. This brings and increased risk of winter hazards, especially frost, and fog or freezing fog which may be slow to clear. When any frontal systems do push across the UK there will be an increased risk of snow. Temperatures are likely to be below normal, and often cold.
