Thu 4 Dec Wales

Changeable and often unsettled conditions are expected to affect the UK during this period. The most likely weather pattern is one of successive areas of low pressure moving in from the west or southwest and then tending to become rather slow-moving in the vicinity of the UK. This means a story of showers or longer spells of rain, with almost anywhere seeing some heavy rainfall at times, but the greatest chance of wetter than normal conditions will be in the west. Any snowfall is most likely over higher ground in the north. Strong winds are also a possibility from time to time, again perhaps more likely in western areas. Given the changeable pattern originating from the Atlantic, temperatures will most likely be close to or a little above normal.
