A visually striking weather map has revealed the anticipated trajectory of a 500-mile blizzard set to sweep across the UK amid dropping temperatures. According to the Met Office, an Arctic Maritime air mass will usher in colder weather conditions from northern Scotland moving southwards, bringing snow and rain across extensive areas of the country. The most intense and widespread snowfall is expected early on Sunday.
The map highlights a continuous 500-mile stretch of snowfall from Aberdeen in the northeast to Cromer, Norfolk in the east, along the North Sea coastline. Regions like Leicestershire and Northamptonshire in the Midlands are predicted to experience snow showers by 6 am.
The heaviest snowfall is forecasted for the North York Moors and the Yorkshire Dales, with other areas likely to see minimal accumulation. Higher ground locations above 200 meters in Scotland and northern England may witness 2-5cm of snow, with elevations above 300 meters possibly receiving up to 10 cm. As the snow and rain move southward, temperatures are expected to rapidly decrease, potentially leading to icy conditions on untreated surfaces.
Persistent blizzards are anticipated in North Yorkshire and East Yorkshire until mid-morning, with the adverse weather conditions expected to continue into the following week. Approximately 38 inches of snowfall are projected to impact 24 cities as far south as Worcester and Peterborough, with Scotland facing the brunt of the severe weather, especially in the Highlands.
Temperatures are set to plummet over the weekend, with parts of the East of England and North Yorkshire expected to feel as cold as -8C on Sunday. Despite the air temperature hovering around freezing, the presence of a strong southwesterly wind will make it feel even colder.
Netweather forecaster Nick Finnis mentioned in a blog post that the band of precipitation will clear eastern areas on Sunday morning, followed by a temporary period of drier conditions before showers, potentially wintry over mountains, spread eastward.
The combination of snow and rain is likely to heighten the risk of flooding, which has already caused damage to homes and businesses in Worcester, Tewkesbury, and other locations along the River Severn this month. Numerous flood alerts are currently in effect, including concerns for groundwater in the Cerne Valley in Dorset.
