Warning Text:
Showers of hail, sleet and snow on Tuesday evening and overnight are likely to leave a covering of snow of 3 – 6 cm in places, especially on ground over 100 m but also locally to lower levels too, whilst 10 cm or so could settle above 300 m. This is most likely to occur in the west of the yellow area, with the high ground of Wales, the moors of SW England, the Mendips and Cotswolds at greatest risk of snow accumulations. A lower risk exists across southeast England early on Wednesday morning. Icy stretches will also form on untreated surfaces. The public should be aware of the risk of tricky driving conditions.

This is an update to extend the warning area further east across southern and southeast England.

Chief Forecasters assessment:
A cold westerly airstream will spread across the area on Tuesday evening, allowing frequent showers in the overnight period to fall as snow, especially over high ground. There is some uncertainty over how much snow will settle at low levels, and many places within the yellow area may miss the snow altogether. However, where snow does occur it is likely to be heavy and produce a covering quite quickly.

Coastal areas facing west or southwest will probably miss most of the snow, but hail and lightning will be hazards here, along with gusty winds.

This warning will be kept under review and updated as and when necessary.
