The warning covers most of the Higher Ground in Wales, whilst the South Wales coastline is covered by a Yellow Weather Warning.
The Met Office has issued an Amber Warning for snow and ice for much of Wales from 6 pm on Saturday until midnight on Sunday.
Whilst the Amber Warning only covers a small part of the Vale of Glamorgan along the M4 corridor, a Yellow Warning for snow and Ice covers the area, along with the rest of Wales from 12pm on Saturday until midnight on Sunday.
For the Vale of Glamorgan, the Met Office says outbreaks of rain spreading progressively northeastwards later on Saturday and overnight into Sunday will likely be preceded by a spell of snow on its northern flank. Whilst there is some uncertainty, any snow in southern and eastern parts of England, especially at low levels, will probably be rather transient before turning back to rain.
However, some significant accumulations of snow are possible across parts of Wales, the Midlands and northern England in particular, at least for a time, where 5 cm or more could accumulate fairly widely, with perhaps as much as 20-30 cm over the higher ground of mid and north Wales and potentially 30-40 cm over parts of the Pennines. This, accompanied by strengthening winds, may lead to drifting of lying snow.
In addition, as milder air moves northwards, snow may turn to a spell of freezing rain for a time, again more especially across parts of Wales, the Midlands and northern England, adding to the risk of ice and leading to some treacherous conditions in places. A fairly rapid thaw of lying snow is possible later on Sunday, although exactly how far north the rapid thaw will reach remains uncertain at this stage.
