The Met Office say an area of snow is expected to extend northeastwards from Wales and into parts of Merseyside on Tuesday evening and night, persisting into Wednesday morning.
Accumulations of 3-8 cm are likely in places, perhaps 10-15 cm very locally on high ground.
The snow should ease gradually through Wednesday morning.
The public should be aware of the risk of disruption to transport.
A chief forecaster for the Met Office has said: “A complex frontal system is running into the UK from the west and is coming up against a stagnant cold airmass on its forward flank over central and eastern areas.
“Rain arriving in westernmost areas will readily turn to snow as it comes inland later on Tuesday, spreading into Wales along with central and northern England overnight.
“The snow is likely to accumulate easily, given the cold ground surfaces.
A Met Office spokesperson also commented: “Today will stay dry and very cold, with temperatures not reaching above two degrees.
“From about 8pm tonight there will be light snow and this will get heavier from midnight.
“It will continue to fall until about 7am so expect a covering when you wake up.
The Met Office say details remain uncertain regarding the extent and amount of snowfall, in particular the northward extent of snowfall into northern England (indeed some areas may miss the snow altogether).
The warnings are in place from 4pm tonight until 12pm tomorrow.
The warning comes as temperatures have plummeted across the region.
Last night Wirral saw the coldest night of the year which froze over lakes and ponds in the area.
