The Met Office has issued the following warning: -
Rain will turn to snow, initially on high ground this afternoon, but increasingly to lower levels. The risk of snow will extend southwards into northern parts of England this evening. 10 to 20 cm of snow could accumulate above 200 metres within the warning area and some places at lower levels could see 5 to 10 cm of snow by Thursday morning. Snow is likely to slowly die out through tomorrow afternoon.
Met Office Chief Meteorologist, Paul Gundersen, said; “There is cold air from the north pushing down the east side of the UK and warm air moving in from the west. Where these two air masses meet a weather front is bringing some heavy rain which is turning to snow in places.
The current, more widespread, yellow warning for snow and ice is valid until 9pm tomorrow evening. It covers the risk of snow and sleet this afternoon across large parts of northern England and Scotland, as well as the risk of ice with rain falling on frozen surfaces overnight tonight and tomorrow morning.
There is a continued risk of wintry, unsettled weather into next week as warm and cold air continue to battle it out above the UK and weather fronts try to make headway across the country. A yellow snow and ice warning has already be issued for Saturday covering large parts of Scotland and northern and central England.
