Two more weather warnings have been issued by the Met Office.
The first yellow warning for ice will be in place for the region from 4pm on Wednesday until 10am on Thursday.
Travel disruption is predicted and the Met Office also warns of potential injury due to slips and falls on icy surfaces.
Meanwhile, the North East has been told to expect "bitterly cold" temperatures and possibly more snow.
The weather warning states: "Further showers are likely on Wednesday evening and overnight, before becoming confined to East Anglia on Thursday morning.
"As ground temperatures fall below freezing there is the likelihood of ice forming on some untreated surfaces.
"Some of the showers may be wintry inland but the chance of any more than isolated very small accumulations of snow is very low."
What to expect
- Some injuries from slips and falls on icy surfaces
- Probably some icy patches on untreated roads, pavements and cycle paths
A second yellow warning for ice will be in place from 5pm on Thursday until 11am on Friday.
It says: "Showers, a mixture of rain sleet and snow, are expected to fall onto frozen surfaces leading to icy stretches forming. In addition, a more persistent spell of rain and hill snow is likely to spread south across northern England and north Wales during Thursday evening and night.
"Whilst ice is expected to be the main hazard, snow is likely in place too. Snow is most likely to fall over The Pennines, North York Moors and the high ground of Wales, with 1-3 cm possible here. Elsewhere, whilst some snowfall is possible, accumulations are likely to be slight and temporary."
