New snow maps have revealed intense blizzard conditions sweeping across the UK this week, with widespread snow showers blanketing the nation and 47 regions currently under alert.
The Met Office has issued additional warnings as the first snowflakes of autumn 2025 coat various areas, including a reported 7cm accumulation in Lake Vyrnwy, Powys, Wales. Predictions indicate that up to 25cm of snow could accumulate by the week’s end, extending as far south as London.
Upcoming forecasts suggest that Thursday will witness some of the heaviest snowfall experienced by many Britons this year. WXCharts’ latest maps depict purple patches indicating snow showers developing along the coast from Wednesday evening, with the most intense snowfall anticipated off the northeast and southwest shores. Areas like Wales and Plymouth might experience snowfall rates of up to 15mm per hour, with even higher levels north of the border.
Regions stretching from Aberdeen to Newcastle along the east coast are expected to face snowfall rates of up to 80mm per hour, although a significant portion is likely to fall over the sea. Smaller snow showers are anticipated across various coastal regions, moving southward from Thurso in northern Scotland to Plymouth.
Overall, snowfall is expected to cover a distance of 748 miles, tapering off by early Friday morning around 9 am off the southeast coast. The Met Office has reinforced this outlook with ongoing weather warnings for 47 areas until late Thursday night, including a rare amber snow alert.
The amber alert, the most severe among the seven alerts this week, warns of frequent wintry showers affecting Yorkshire, potentially leading to widespread disruptions and isolated communities being cut off between 3 am and 9 pm the following day. Residents in Redcar and Cleveland, East Riding of Yorkshire, and North Yorkshire have been cautioned about gusty winds and lightning strikes accompanying the freezing conditions.
The forecast for Thursday by the Met Office indicates a predominantly sunny day for most areas, with coastal regions experiencing sleet and snow showers, especially heavy in northeast England. Cold temperatures are expected with widespread frost redeveloping overnight.
Looking forward to Friday and the weekend, the forecast suggests the arrival of rain and cloud from the west on Friday and Saturday. The weekend is expected to be milder with further rain spells on Sunday, interspersed with some brighter intervals.
