Torrential rain and snow will make it a miserable Easter Monday as thousands of Britons head home after the four-day weekend.
Up to six inches of snow is forecast for much of Wales, northern England and Northern Ireland.
South of these areas are expected to see heavy downpours for much of the day.
Some parts of the country could get as much as 70mm of rain and drivers returning home have been warned to expect treacherous conditions.
Temperatures dipped as low as minus 7C (19.4F) in the Scottish Highlands overnight while torrential rain moved in from the south and west amid milder conditions.

Torrential rain today will make for difficult driving conditions and the wet weather will continue
More than 100 flood alerts and seven flood warnings were in place across England yesterday.
The deluge follows a similar one on Good Friday, which led to football match cancellations and a miserable start to the holiday throughout the south.
Yellow snow alerts for parts of northern England and Scotland were also issued, with as much as 15cm predicted to fall on higher grounds.

Around 150 flood alerts and 15 flood warnings were in place across England on Monday morning.
Some rural communities could become cut off, mainly across the northern Pennines and Scottish Borders, with ‘significant accumulations’ and up to 10cm of snow forecast.
The cold and wet weather comes from a weather system travelling from the south west.
This morning, heavy rain and strong winds across the south of England will spread slowly northwards.
As it reaches colder conditions around the Midlands, it may well change to snow.
It means there could be delays on the roads, with a risk of stranded vehicles and disruption to rail and air travel.
But fortunately the end of the week looks set to be far warmer, with the possibility of high-teen temperatures in the south by Friday.

Forecaster Helen Roberts said: ‘The main risk is rain, we have a number of warnings out at the moment, including a fairly large rain warning covering most of the country.
‘It is going to cause problems for people travelling on Monday – there will be a lot of surface water on roads.
‘Further north there is a snow risk overnight on Sunday with snow and sleet across the moors of England and hills and mountains of wales.’
She added: ‘There could be some disruption in the north.
‘Further south it will be more of a transient feature and not much settling on the roads.’
Snow is not uncommon in April, with the month seeing an average of 2.3 snow days each year.
For those who are travelling across Britain, warnings have been issued that train services could be disrupted and heavy traffic will take to the roads.
The AA warned motorists to take extra care and said the bank holiday weekend is ‘likely to be one of the busiest on the roads in recent years’.
Forecasters have warned of treacherous driving conditions for Easter holidaymakers with snow and torrential rain on the way. Much of the UK has been issued with yellow warning for torrential rain
This year, the UK saw a particularly cold spell, as icy cold winds from Siberia carried heavy snow.
The heavy snow, which fell and settled in large parts of the country was dubbed the ‘Beast from the East’.
But fortunately, tomorrow and the rest of the week look set to be warmer and more pleasant.
On Tuesday, the cold weather system is set to travel up to Scotland.
And later on in the week, temperatures could climb even higher.
‘By Friday there is the possibility that temperatures in the South could climb into the late teens,’ said the forecaster.
‘This doesn’t mean there will be no more wet and cold weather though.’
