There is a 90% probability of severe cold weather/icy conditions/heavy snow between 1500 on Friday and 1200 on Wednesday in parts of England. This weather could increase the health risks to vulnerable patients and disrupt the delivery of services. Please refer to the national Cold Weather Plan and your Trust’s emergency plan for appropriate preventive action.
Low pressure, tracking southeastwards over central and southern England later Boxing Day and overnight into Saturday 27th, is expected to give a period of sleet and snow across the Midlands, some northern parts of East Anglia and southern parts of both NW England and Yorks and Humberside. Some significant snow accumulations are possible, especially on higher ground. Strong winds will develop in places for a time, exacerbating the chill. As the low clears away southeastwards, cold air will move south across the whole of England giving a risk of wintry showers and icy conditions across England for the rest of Saturday. Sunday to Tuesday, high pressure brings lighter winds but with widespread night frosts and freezing fog patches which may linger well into the day in places. The combination of both night time sharp frosts and daytime low temperatures gives a high probability of mean temperatures widely 2 degrees Celsius or lower. Later Wednesday, strengthening southwesterly winds may lift temperatures across northern England but it is likely to remain cold elsewhere.
