The United Kingdom is preparing for a significant winter weather event, with forecasters predicting a staggering 326-mile band of snow to hit the country. This substantial snowfall will be accompanied by two rare meteorological phenomena: thundersnow and freezing rain, creating potentially hazardous conditions across many regions.
Rare Weather Phenomena Explained
Thundersnow, an unusual event occurring approximately ten times per year in the UK, is expected to strike in the coming days. This dramatic weather phenomenon combines thunder and lightning with heavy snowfall, creating an impressive but disruptive natural display. Alongside this, freezing rain is anticipated, which the Met Office describes as a rare type of liquid precipitation that freezes almost instantly upon striking cold surfaces.
Weather projections from multiple sources including Ventusky, Netweather TV and WX Charts – which utilises Met Desk data – have revealed these unusual weather patterns. The forecasts are based on the advanced GFS weather system model, indicating 8mm of rain is expected alongside the freezing conditions.
Detailed Weather Timeline and Impacts
The most severe weather is forecast for Tuesday, November 18, and Wednesday, November 19, according to Met Office warnings. Met Office presenter and meteorologist Aidan McGivern provided a detailed breakdown: "We start off Tuesday with a real mixed bag across the UK. We've got plenty of showers into Scotland, Northern England, Northern Ireland. Again, some upland snow for Scotland and further showers for the south of England."
McGivern noted that while some areas might experience sunshine, particularly through Wales, the Midlands and eastern England, the situation deteriorates into Tuesday evening. "Those showers becoming more prolonged, heavier at times as well," he added, with blustery winds particularly affecting western Scotland and Northern Ireland.
Extended Forecast and Official Warnings
The cold spell is expected to intensify towards the middle of the week. Met Office deputy chief forecaster Tom Crabtree stated: "Wednesday to Friday will be the coldest part of the week, and this period has the greatest potential for impactful weather, with multiple warnings in place." He warned that overnight temperatures could plummet to minus 10°C, with significant wind chill from strong northerly winds making conditions feel even colder.
The BBC Weather team confirms that Thursday will continue the pattern of cold, windy conditions with sleet and snow showers expected in northern Scotland, North Sea coasts, and along west Welsh and south-west English coasts. Residents across affected regions are advised to prepare for travel disruption and take necessary precautions during this period of unusually severe winter weather.
