Yellow warnings for snow and ice are in place across the east Midlands and south east, with an amber alert bracing the east of England.
The fresh warning affects Cambridgeshire, Essex, Hertfordshire, Norfolk and Suffolk and towns in those regions could become cut off.
The warning states: “There is a good chance that some rural communities could become cut off.
“Power cuts are likely and other services, such as mobile phone coverage, may be affected.”
East Anglia, Kent and Sussex are expected to see heavy snowfall for the longest period of time.
For Scotland and Northern England, the Met Office said snow levels could rise to above 300m.
It forecasts: “An area of rain pushing eastwards is expected to turn to snow in places.
“Snow is likely to fall to low levels over east Scotland and northern England for a time on the leading edge of the rain before the snow level rises to above 300-400m by mid morning.”
The Environment Agency has issued 32 flood warnings across England, with Leicestershire and Essex among regions suffering the worst of the heavy rains this week.
In addition to floods, forecasters have warned snow and ice could cause travel chaos, with the potential to leave vehicles stranded and rural communities cut off.
“1-3 cm of snow may fall fairly widely over these areas with 5-10 cm possible in places, mostly over parts of East Anglia and any higher ground.
“Given recent wet weather and high river levels with rain and snow falling, then melting some flooding impacts are also possible.”
Chief Meteorologist Steven Ramsdale, said: “Whilst the high ground in the north is likely to see the largest accumulations, some snow is likely to fall to low levels at times.
“In fact, parts of east England and East Anglia look most at risk of seeing 1-3 cm with 5-10 cm possible in places.
“The milder air will eventually win out with the initial snow gradually turning to rain. This may also bring some flooding issues following recent wet weather and with snow then melting – though the snow looks to be the greater hazard.”
It comes after temperatures plunged to -11.8C in north Yorkshire on Thursday night, with the whiteout causing chaos throughout the day.
A major incident was declared by the Yorkshire Ambulance Service after heavy snow and a surge in patient demand hit hard.
Meanwhile, early risers were seen scooping snow from their driveways in County Durham, as drivers battled to steer through the white stuff in Northumberland and Yorkshire.
In Leicester and Essex, cars faced a different struggle, making their way through floodwater after heavy rain fell in parts of the country overnight.
One driver suffered the worst of the treacherous conditions, their car pictured smashed up against a tree in Leeds.
And terrifying footage showed a bus spinning down a hill in Halifax, West Yorks.

Met Office recordings showed 11cm of snow falling in Strathallan, Scotland, yesterday, while parts of Northumberland saw 10cm of the white stuff.
Albemarle in West Yorks, recorded 9cm, although the figures off record could be much higher.
“Looking at people’s pictures from today, it could be 15cm,” Met Office forecaster Greg Dewhurst told the Sun Online.
“The heaviest snowfall has passed now and it will gradually ease as we go through to this evening. But it wouldn’t surprise me if a couple more places see another 2-5cm.”
