Reason for update
The warning has been updated to make this a dual snow/ice warning with the area extended southwards across more of central and southwest England. The warning end time has also been delayed until the end of Friday.
Showers, a mixture of rain sleet and snow, are expected to fall onto frozen surfaces leading to icy stretches forming. In addition, a more persistent spell of rain and hill snow is likely to move south across northern England and north Wales during Thursday evening and night. This then gradually moving into parts of central and southwest England and southeast Wales on Friday. Whilst ice is expected to be the most widespread hazard, snow is likely in places too. Snow is most likely to fall over The Pennines, North York Moors and the high ground of Wales and southwest England, with 2-5 cm possible here. Elsewhere, whilst some snowfall is possible, accumulations are likely to be slight and temporary. Freezing fog patches are also likely to persist and may prove an additional hazard with areas of visibility less than 100 m at times.
