A yellow weather warning for snow comes into force on Wednesday afternoon, but we’re likely to see some snowfall before then
The Met Office has issued a weather warning for snow with forecasters cautioning that significant disruption could affect substantial parts of Wales on Wednesday and overnight into Thursday. The yellow warning predicts that a spell of rain and snow may cause disruption across most of the country for 14 hours.
Meteorologists have highlighted the possibility of settling snow, especially across higher ground. The warning – which will be in place between 4pm on Wednesday and 6am on Thursday – covers Blaenau Gwent, Bridgend, Caerphilly, Carmarthenshire, Ceredigion, Conwy, Denbighshire, Gwynedd, Merthyr Tydfil, Monmouthshire, Neath Port Talbot, Newport, Pembrokeshire, Powys, Rhondda Cynon Taf, Swansea, Torfaen and Wrexham.
Snow accumulations of 2-5cm could develop relatively widely across locations above 150-200 metres, with potentially 10-15cm above 250-300 metres throughout parts of mid and south-east Wales. Read the biggest stories in Wales first by signing up to our daily newsletter here.
Lighter accumulations, generally under 2cm, may occur at lower elevations, particularly from late Wednesday evening into the early hours of Thursday.
Strong easterly to north-easterly winds are anticipated alongside the snowy weather, potentially worsening conditions in certain locations, especially on roads.
According to the Met Office, Wednesday could see 2-5 cm of snow accumulate quite widely above 150-200 metres, with perhaps as much as 10-15 cm above 250-300 metres in mid and southeast Wales.

Met Office Deputy Chief Forecaster Steven Keates explained the outlook: “On Wednesday, weather fronts are expected to move in from the Atlantic into some western, southern and central areas of the UK.
“As they bump into the cold air already in place, we are likely to see some snow developing, although there is still some uncertainty around the details.
“Initially, we may see some snow over the highest parts of southern England, such as Dartmoor, but the main chance of snow will be across higher parts of the Midlands and mid and southeast Wales.
“Above 150 to 200 metres, 2–5 cm of snow may accumulate, with a few places -most likely above 300 metres -possibly seeing 10 cm or more.
“Temperatures will be around 3 to 5 °C for much of the UK on Wednesday.”
