Temperatures will plummet in Wales after weeks of heavy rain. Rain or showers will ease over the weekend with bright spells and dry spells as high pressure is likely to settle over the UK or just the north of the country.

The Met Office says the weather will change for most, with the weather moving into a cooler, drier and more stable period. The forecast agency says next week will be quite cold, with temperatures below average across much of the country. Frost is likely to occur overnight and, given the wet ground, calm conditions and long nights, there is also a risk of fog and ice.

Dyfed Powys Police warned of “treacherous” conditions in north and central Powys on Friday morning (January 5) due to ice.

BBC Wales weather presenter Sue Charles says the weekend will be “drier but cooler”, adding: “Maybe some showers on Saturday, but mostly light and dry. “Sunday will be a little cloudier and cooler, brighter in the west, with overnight frosts returning.”

Long term forecast for the UK from From Tuesday 9th January to Thursday 19th January, sunnier weather is suggested to occur in the north and west. There is also an “increasing chance” of snow in some parts of the UK.

The forecast adds: “By the middle of next week the winds are expected to decrease and the weather is expected to be dry with high pressure. Clouds will remain quite variable, but all areas should be sunny at times. Much colder than recently and frost is likely to become quite common, with areas of freezing fog possible. Conditions will likely remain cold beyond next week, with an increasing chance of some snow showers forming, especially in the north. “

An even broader forecast for early February says there is a “higher likelihood of cooler conditions” during this period than normal.

It’s still too early to say for sure, but the forecasting agency says: “For now, the chance of widespread severe cold is still considered low, but the risk of cold weather, including ice and snow, is above normal.” “It will be drier than the last few weeks, but the fall will likely be wintry.”

Adding: “While there is a chance that short, irregular periods will bring milder air for a while, it is also likely that this will be accompanied by a period of sleet or snow. However, it is very uncertain when this will happen, or even if it will happen, and in general the main question will depend much more on the conditions established during this period.
