A brief show of sunshine over the weekend has given way to further rain, with flooding expected in more than 70 areas.
Rain is likely to turn to snow and sleet across parts of eastern England, where a yellow snow warning is in place on Sunday between 10am and 4pm.
Sunday's rain, sleet and snow will clear eastwards followed by sunny spells and blustery showers from the west.
While some isolated patches of wet snow might linger over parts of East Anglia, in most places road temperatures will be too warm to allow snow to settle, said Kirsty McCabe, Sky News' weather producer.

Some of the showers will be heavy and prolonged with risk of hail and thunder.
There were 74 flood warnings and 162 flood alerts in place across England on Sunday morning, with the Environment Agency urging the public to remain vigilant amid the ongoing flood risk.
Jonathan Day, flood duty manager at the Environment Agency, said about 330 homes and businesses have been flooded, while 24,000 have been protected by flood defences.
The snow warning for eastern England said "a spell of snow may lead to some disruption to travel".
It added: "Rain moving eastwards through Sunday morning is likely to turn increasingly to sleet and snow.
"Slushy accumulations of 1cm or so are likely, with a chance of 2-4cm should snow turn briefly heavier, this more likely for the Lincolnshire Wolds and parts of Norfolk and Suffolk."

Met Office meteorologist Greg Dewhurst said Sunday will have a blustery start for many and outbreaks of showery rain, with some hill snow.
Milder air will move into the South West and parts of Cornwall and Devon could reach 12C, while it will be about 4C or 5C in the east, he said.
Monday will bring more widespread blustery showers, before a drier start to Tuesday which will later give way to more wet weather.
