Information on update: The warning area has been expanded eastwards to cover a more widespread risk of ice, whilst snowfall amounts have been reduced. Scattered rain, sleet and snow showers across Wales and western parts of England may feed further east during Tuesday morning. Whilst not all areas will be affected, some small snow accumulations are possible, with the greatest chance across high ground of Wales where 1-3 cm could accumulate in a few places. Elsewhere, mostly negligible accumulations are likely, but up to 1 cm is possible in one or two places. With temperatures widely below freezing, icy surfaces are likely.
