UK snow maps show 64cm blizzards as far south as Devon

Published: Wed, 18 Feb 2026 15:04:27 GMT UK, By: Titus Avery

If you’ve started penciling in a grey, wintry weekend on the calendar, you’re not alone. Forecasts from WXCharts are stirring up conversations about a rare and dramatic snow event that could sweep across parts of the UK next weekend. In this scenario, some Scottish regions might wake up to substantial snow depths, while southern counties like Devon could see light, but still notable, flurries. The big question isn’t just “will it snow?” but “how much and where will it settle?”

While forecasts can change as new data pours in, the current model runs suggest a striking contrast: up to 64 cm of snow in certain Scottish high areas, and around 2 cm near Plymouth in Devon, with Southampton and parts of Hampshire possibly catching a light dusting. If these numbers hold, we’d be witnessing a weather event that would disrupt daily life in several regions and test how households, road networks, and local services respond to rapid cold snaps. Here’s what that could mean for you and practical steps to stay warm, safe, and prepared.

Understanding the forecast: what WXCharts is telling us

Before you rush to the shops, it helps to unpack what these forecasts really imply. WXCharts uses a mix of global and regional weather models to project snowfall, wind, and temperature. Snow depth forecasts — the 64 cm figure in Scotland, for example — are a function of initial moisture, air temperature, humidity, and wind. They’re highly sensitive to shifting conditions and can change as new data streams in.

Here’s a quick mental model you can hold: think of snow forecasts as a weather map of potential outcomes. A forecast of 64 cm in the highlands doesn’t mean every town will wake to that depth, but it signals a high likelihood of heavy snowfall in sustained cold air, with winds that can enhance drift and reduce visibility. In contrast, the southern estimate of around 2 cm suggests lighter, possibly flurry-like snow that’s unlikely to accumulate heavily on treated roads but can still weave its way into roadsides and pavements.

Forecast accuracy is improved by multiple models agreeing on a scenario and by continuous updates as the weekend approaches. If you’re planning travel or outdoor activities, it’s wise to check official forecasts closer to the weekend and prepare for changes in a hurry. And if you’re concerned about how your home will handle a snow event, reading up on heating performance and insulation becomes a smart, proactive step.

Regional impact: from Scotland to Devon

Scotland: a snowy spectacle

In Scotland, heavy overnight and daytime snowfall is where the forecast attention shines. The mountains and northern regions could see deep accumulations, with prolonged snowfall periods that persist through the day. What sounds dramatic on paper translates to practical realities: roads through high passes might close, rural routes could become impassable, and communities may need extra warming shelter and delivery support. For households in these areas, planning ahead is essential—think extra fuel for heating, ensuring proper carbon monoxide detectors, and keeping a clear path to front doors and driveways in case clearing is needed.

As always with Scottish winter weather, wind can magnify the impact by creating blizzards and blowing snow into drifts that bury access routes. If you live in or near mountainous terrain, you’ll want to stay tuned to local updates and have a plan in place for school closures or service interruptions.

Devon and southern England: lighter but notable snow

Further south, the forecast paints a very different picture: light snow that can still cause disruption, especially in urban areas unaccustomed to frequent snowfall. In Devon near Plymouth, forecasts suggest around 2 cm of accumulation in some spots, which can still blanket roads and pavements and lead to slippery conditions for commuters and pedestrians alike. While not as dramatic as deserting a 64 cm depth, that degree of accumulation can still affect school timings, travel plans, and local business operations.

Coastal counties should also be mindful of winds funneling off the sea, which can pile snow into small localised drifts and create patches of ice on untreated surfaces. It’s worth noting that even small amounts of snow can surprise drivers who aren’t used to winter road conditions, so a cautious approach to travel is wise.

Southampton and Hampshire: a dusting potential

Southampton and parts of Hampshire appear likely to see a light, early-season snow event if the forecasts hold. A dusting can still create slick pavements, reduce visibility, and trigger early closures in some places. For residents and visitors, it’s a reminder that weather patterns aren’t uniform and that planning for variable conditions pays off: have a warm coat ready, shoes with good grip, and a small emergency kit in your car if you must travel during wintry spells.

What accumulating snow means for homes and heating

Heavy snow isn’t just a curiosity; it tests the heartbeat of a home—your heating system. A rapid drop in temperature places a premium on reliable warmth, which in turn heightens attention on boilers, radiators, insulation, and energy costs. When outside temperatures plummet, the demand for heat surges. That can strain the heating system, especially if it’s older or undersized for your home’s layout. You’ll want your boiler to be healthy and efficient, your radiators to heat evenly, and your home to stay snug without turning into a dry, overheated furnace.

Preparation matters as much as the forecast. Simple checks now can prevent cold nights and expensive energy bills later. Start with a quick system health check: is your boiler serviced recently? Are you bleeding radiators to remove air blocks? Are your thermostats and timers calibrated for efficient operation? If you need expert help, there are specialists who can assess and optimize your setup. For instance, a professional service can identify if any parts are nearing fatigue and propose a plan to keep you warm through a long winter spell.

Two practical steps can make a big difference. First, consider a power flush to clear out limescale and sludge from your central heating system, which helps radiators heat more effectively and reduces energy waste. For guidance and service, you might want to explore Powerflush, a resource that explains how a clean heating system transfers heat more efficiently. Second, if your boiler is older or showing signs of strain, speaking with a reputable heating professional—someone who can recommend modern, efficient replacements or controls—can save you money and stress in the long run. A trusted local option is Harrow Heating, which offers boiler repairs, installations, and maintenance across many UK regions.

In addition to professional help, there are home-based steps you can take. Insulate and seal gaps to prevent warm air from escaping, keep curtains drawn at night to reduce heat loss, and use programmable thermostats to maintain consistent warmth. If you’re worried about energy costs during a cold snap, a modest investment in insulation or a programmable control system can yield long-term savings—often faster than you’d expect.

Practical tips for staying safe and warm

When snow blankets the landscape, safety comes first. Here are practical moves that can help you stay warm and avoid trouble:

Dress in layers and keep a reliable indoor temperature—ideally around 18–21°C (64–70°F) for comfort and health.
Prepare a small winter kit for the home and car, including blankets, a flashlight, a battery bank, and non-perishable snacks.
Keep a buffer of hot water ready for drinks and quick meals; heat a kettle for tea or soups to maintain comfort during outages.
Regularly check smoke and carbon monoxide detectors when using alternative heating sources or generators.
Have a plan with neighbors or friends to assist anyone vulnerable during severe cold snaps.

For homeowners concerned about boiler efficiency in extreme cold, routine maintenance, attention to water quality, and ensuring circulation are crucial. If your heating system is older or you’re looking for a robust improvement, it’s worth exploring options with heating professionals who can tailor solutions to your home’s needs.

Travel and infrastructure considerations

Snow doesn’t just affect homes; it reshapes the rhythm of daily life. Roads can become hazardous, schools may close, and public transport schedules can shift dramatically. Even a light dusting can slow traffic, while heavy snowfall can trigger road closures and delays. If you’re planning weekend trips, keep an eye on live travel updates and allow extra time for journeys.

Practical preparation for travel includes packing essentials, keeping a charged mobile device, and ensuring your vehicle is winter-ready with a full tank of fuel, antifreeze, a scraper, and a warm blanket. If you’re responsible for a business or school, consider contingency plans for closures or remote work when weather patterns swing to extremes.

Local authorities and transport agencies usually publish guidance during winter events. Checking regional updates can save you headaches and keep commutes safer for everyone on the road. If you’re curious about heating in a snow-prone setting, the same home comfort principles apply: stay warm, stay informed, and lean on trusted professionals when needed.

Historical perspective: how the UK handles heavy snow

Britain’s climate has always flirted with cold snaps, but large snowfall events across broad regions are still relatively rare in some areas. Every year brings a different pattern: some winters produce heavy snow in the north and inland areas, while others bring more moderate conditions even where forecasts hint at the possibility of large accumulations. The unpredictability is what makes preparedness so important. People adapt by stocking essentials, maintaining heating systems, and staying connected to reliable forecast sources, so they’re not caught off guard if winter’s mood shifts.

Historically, communities learn to respond quickly: schools adjust schedules, suppliers prepare for higher demand, and residents keep extra fuel and essentials on hand. The combination of prudent planning and responsive services is key to navigating a winter that can surprise us with both dramatic and delicate snowfall patterns.

What to do now and in the days ahead

The best approach as forecasts hint at a snowy weekend is proactive rather than reactive. Here are practical steps you can take today:
