Mostly dry, cold and bright to end the week.
A cold and frosty start, but a fine day in prospect with long spells of sunshine, especially in the east. Cloud will thicken across west Wales where it will begin to turn breezy. Elsewhere, light winds but feeling cold. Maximum Temperature 5C.
Quickly turning cold for a time in eastern Wales with a frost developing. Otherwise, becoming cloudier and windier with sporadic outbreaks of rain arriving for most through the night. Minimum Temperature -1C.
Rain soon turning heavy and persistent with gales, especially around coasts and hills. Feeling cold, emphasised by the strong winds. Maximum Temperature 7C.
Outlook for Sunday to Tuesday:
Less cold on Sunday with sunshine and showers, especially later. Risk of ice early on Monday, otherwise mainly dry. Turning windy on Tuesday with rain, perhaps becoming persistent.
Day 6 to 15
Cloud and rain should clear east early on Wednesday with sunshine and blustery showers following. The showers most frequent in the northwest and west where there is the risk of hail and thunder with some hill snow in the north. Some patchy fog may be slow to clear on Thursday with fewer showers and lighter winds. It is then likely to remain mostly unsettled through the rest of the period with spells of rain and strong winds. The heaviest rain will be in the west with eastern parts staying generally drier. With the unsettled weather temperatures are likely to be around or a little above average. However, there is a small chance of a colder and shower spell developing during Christmas week.
Day 16 to 30
The start of this period is most likely to be unsettled with the continuation of wet and windy weather pushing in from the west. Through the first half of January there is an increasing likelihood for it to turn colder bringing the increased risk of winter hazards, especially frost and fog. Some snow is also likely with temperatures expected to fall below normal. However, there is uncertainty in the timing of this change to turn colder, and it could come before the end of December.
