As the weather breaks down, an area of snow looks increasingly likely to spread from the southwest. Winds will strengthen and blizzard conditions are a possibility, especially over high ground. Accumulations of more than 10 cm of snow are possible in many parts, with the potential for some severe disruption, though currently there is a good deal of uncertainty about intensity of snow and how quickly it will turn to rain in the southwest.
The public should be aware of the risk of significant travel disruption affecting the west in the morning and the east in the afternoon. This warning is likely to be updated over the next couple of days.
A frontal system is expected to move northeastwards across much of the UK during Friday. There is quite a lot of uncertainty about the progress of this front and the balance between rain and snow, especially for western areas. Some parts especially southern and western coastal districts, rain may fall instead of snow.
