A severe weather warning for snow has been issued across the country and could affect UK military bases.
The following regions have been issued yellow warnings.
- South West England
- East of England
- London & South East England
- West Midlands
- East Midlands
Rain moving eastwards across the south of the UK on Thursday may turn to snow in places.
There is a chance of snow settling with disruption to road, rail and air services as well as interruptions to power supplies and other utilities - this is more likely across East Anglia and south-east England.
Associated heavy rain and strong winds may prove additional hazards.
As skies clear on Thursday night there is also potential for widespread ice to form quite rapidly on untreated surfaces.
This is an update to slightly increase the risk of disruption from snow, as well as to introduce ice as a hazard.
