Snow is expected to fall on Friday prompting a yellow warning from the Met Office to be aware of potential disruption.
It said rain will turn to snow for a time, mainly over the high ground during Friday morning.
Over low ground it is unlikely that any snow will accumulate but many areas may see falling snow and slushy deposits for a time.
The public are advised to be aware of the potential for some disruption to travel especially during Friday morning rush hour.
An area of low pressure is expected to move eastwards on Friday.
There is considerable uncertainty in its track and therefore on the risk and location of any snow.
