Showers will affect the area during Sunday night and into Monday morning, falling increasingly as snow above 200-300 m with a mixture of rain, hail, sleet and snow to lower levels. Accumulating snow may lead to travel disruption on routes over high ground, whilst icy stretches are also likely to form more generally on untreated surfaces.
The public should be aware of the potential for disruption to travel during Sunday night and Monday morning.
This is an update to extend the warning area further west across Wales and also further south.
Chief Forecaster’s Assessment
Cold air covers the UK with frequent showers pushing into areas exposed to the west to northwesterly winds. These showers falling primarily as snow above around 200-300 m with a mixture of hail, sleet and snow to lower levels.
Accumulations of 2-5 cm of snow are possible around 250 m, with some temporary slushy accumulations below this, and possible accumulations of 5-10 cm above 400 m. Icy stretches are likely to form after showers.
To the east of the Pennines and the Welsh mountains, showers will be less frequent, but road surface temperatures lower, leading to an increased risk of ice following the occasional shower.
