Farmers Weather expert Garry Nicholson said ‘quiet weather’ is expected with day-time temperatures of around 6 to 10C.
The chance of a white Christmas is fairly low as ‘severe gales’ develop towards the Christmas weekend.
But Farmers Weather expert Garry Nicholson said snow should not be ruled out on higher grounds.
Until then, the country is set to see cloud and fog, with drizzle turning to heavy rain as the week continues.
He said: “It will be generally dry over the weekend and into the first part of next week, but a little drizzle is possible at times in the north and west.
“There will be some sunshine, but expect a lot of cloud, and stubborn fog patches are likely.
“Temperatures will be around 6 to 10C by day, although where fog lingers it may stay cooler.
“A touch of frost is possible in some rural areas, but overnight temperatures should stay above freezing for most places.
“By midweek onward, a change will develop as frontal systems move in from the Atlantic, bringing heavy rain to north-western Britain and Ireland,” said Mr Nicholson.
“South-westerly winds will strengthen, reaching gale force in the north.
“Squally showers are likely later in the week, which may turn wintry over the hills as colder air arrives from the north Atlantic.
“Toward the Christmas weekend, there is a threat of severe gales developing, as more active storm systems threaten to move in from the west.
“For most places, the chance of a white Christmas is currently fairly low, but where rain bands interact with colder air in the north, we would not rule out snow over higher ground.”
Farmers Weather videos will be available next Monday and Thursday.
