Showery rain clearing then chilly with clear spells.
This Evening and Tonight:
A band of showery rain will move eastwards this evening, eventually clearing around midnight with some drier and clearer conditions following. Isolated showers may linger on the coasts, while inland it turns chilly with a local frost possible. Minimum Temperature -1C.
A chilly start on Monday with bright spells. Strengthening winds will bring outbreaks of rain from the west from late morning onwards, with coastal gales possible in the west later. Maximum Temperature 11C.
Outlook for Tuesday to Thursday:
Wet and windy on Tuesday, with coastal gales likely. Sunny spells and blustery showers thereafter with hail and thunder possible. Temperatures will be near normal.
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.
