Bitter easterly winds will push temperatures widely below freezing bringing widespread frosts and the risk of wintry showers. High pressure responsible for the cold weather will shift after the weekend allowing milder air to flood in from the Continent. Temperatures are forecast to lift back into double figures with some models showing a chance of 24C (75F) by Easter Monday.
Met Office meteorologist Helen Roberts said: “Quite a chilly start to this Sunday morning but a bright one for many of us.
“The best of sunshine in Scotland will be across more western areas while slightly thicker cloud already begins to make itself known.
“This will be similar in the east.
“In northern England there will be quite a good amount of sunshine.
Ms Roberts added: “Thicker cloud will affect parts of southwest England and west Wales over the course of the day.
“We will start to see cloud bubbling up elsewhere with a few showers across more eastern and southeastern parts of the country.”
The rest of the day is expected to remain largely dry.
There will be more cloud than yesterday.
Next week, temperatures will start to pick up with increasingly warm air.
Ms Roberts said: “A change of wind direction and that will bring increasing warmer air as we head towards Easter weekend.
“For the rest of this week, rain for for some of us on Monday and Tuesday.
“Then it will be largely dry with some sunshine through the latter part of the week.”
