UK snow maps turn purple with snowstorms as far south as Cornwall, Essex and Sussex

The latest forecast maps from WXCharts are painting a chilly picture for the UK this month. If you’ve been glancing at the color-coded weather visuals, you’ll have noticed a shift toward purple swaths—signifying snow is edging southward beyond the usual snowy havens. February 18 and 19 are shaping up to be a turning point, with wintry showers sweeping across parts of Scotland, the north and even dipping into the south. Here’s what this means for families, commuters, and anyone itching for a snowy scene.

What the purple snow maps really indicate

Color on weather maps isn’t just for pretty visuals. It’s a quick way to read the air’s mood. When WXCharts or similar models light up sections of the map in purple, that’s a signal of significant snowfall potential, not merely light flurries. The choice of color helps meteorologists and the public gauge where accumulation could be more than a dusting—where roads may slick over, and temperatures could drop sharply.

For February’s mid-month window, forecasters expect a broad band of wintery precipitation to take shape. The forecast points to snow in the far north and the highlands, then a push into southern and eastern England. In practice, that means more than a few flurries: a snow anniversary for some towns and a reminder to plan for cold, crisp weather and possible travel disruption.

Forecasts are, by their nature, probabilistic. The exact timing and the amount of snow can shift as fronts move and air masses interact. If you’re planning a trip or outdoor activities, keep eyes on updated advisories and be prepared to adjust plans as new data comes in. In the meantime, knowing where the coldest pockets are likely helps you bundle up, check home comforts, and think ahead about heating needs.

Where the cold is headed this week

Scotland and the northern belt

Weather models emphasize a strong push of Arctic air into the Highlands and northern Scotland. Places like Wick, Durness, Inverness, and the Cairngorms could see sustained snow, with risk of gusty winds driving whiteout conditions at times. Central Scotland—think around Stirling, Glasgow, and the surrounding lochs—could settle into the colder end of the scale, with temperatures dipping well below freezing on the chilliest nights.

In practical terms, you might wake up to a winter landscape that makes early commutes feel like mountain ascents. Expect frosty mornings, with thermometers flirting with -2°C to -6°C in many inland zones. Coastal pockets may experience milder readings, but a brisk breeze could still push wind chills lower than the air temperature suggests.

Southern Scotland, the north of England, and the Midlands

Snow isn’t just a northern affair this time around. The forecast puts a swathe of wintry weather across southern Scotland and parts of northern England, including cities like Glasgow, Blackpool, Hull, and neighboring towns. While the heaviest accumulation is more likely toward higher ground or exposed locations, there is a real possibility of fresh powder drifting into coastal and near-coastal towns.

Look for daytime highs hovering near or slightly above freezing in many parts, with night-time lows well below that threshold. This kind of cold snap makes roads treacherous, especially after a light thaw followed by another round of freezing air. It’s a reminder to drive with caution and to keep an eye on local travel advisories.

Wales, the South-East, and the South-West corridor

Temperatures across Wales and southern England could drop to the freezing mark and below in a number of spots. The south of England, including cities like London, Oxford, Bristol, Plymouth, St Ives, and Brighton, might see a mix of snow showers and wintry sleet during the peak of the event. The forecast points to a broad range of 0°C to around 2°C across the region, with some inland areas dipping a touch lower at night.

Even if heavy accumulation doesn’t materialize everywhere, the cold air stays potent. If you’re out and about, plan for slippery surfaces and chilly winds. And if you’re in Cornwall, Essex, or Sussex, you’re not immune to sudden snowfall or flurries that could temporarily blanket roads or pavements.

Temperatures you should expect across the map

• Grampians: as cold as -7°C in the coldest pockets.
• Central Scotland: typically between -2°C and -6°C.
• Most of Scotland: around 0°C to -3°C.
• Wales: generally 0°C to -1°C.
• North of England: a mix from 2°C down to -1°C depending on wind and location.
• Midlands, East Anglia, Northern Ireland: roughly -1°C to 1°C.
• South of England: roughly 0°C to 2°C.

These ranges reflect a broad, day-to-day variability as fronts roll in and retreat. It’s wise to check daily forecasts for your exact town or postcode, especially if you’re planning travel or outdoor activities. The key is to expect change and prepare accordingly.

Why forecasts can change so quickly

Forecasts for a week or two out always come with caveats. Weather systems interact in a constantly shifting dance—the Atlantic jet stream, Arctic air lofts, and local microclimates all play a role. A front that looks like a sure thing on one model might weaken or stall on another run, while a small shift in wind direction could alter snow-accumulation patterns dramatically.

That’s why meteorologists emphasize ensemble forecasts—multiple model runs that test different scenarios. When a piece of the puzzle repeatedly appears across several runs, confidence rises. Otherwise, we watch with cautious optimism and ready ourselves for changes. For residents in the southern stretches of the UK, it’s a reminder that weather can surprise us even when maps show only a light dusting today.

Practical tips for staying warm, safe, and prepared

Cold snaps and snow aren’t ideal, but with smart preparation, you can stay comfortable and minimize disruption. Here are practical steps you can take right now.

1. Boost your home’s warmth and efficiency

Cold weather increases heating demand. If your heating system is older or a bit sluggish, it’s a good time to consider a service check. A well-tuned boiler runs more efficiently and reduces the risk of breakdown when you need heat most. It’s also wise to ensure doors and windows are properly sealed to cut heat loss. Simple steps—closing gaps around frames, adding weather stripping, and keeping internal doors open to circulate heat—can make a meaningful difference.

For heating solutions and professional support, consider reaching out to Harrow Heating. They can provide guidance on maintaining comfort during cold snaps and help you plan for colder months ahead.

2. Mind the pipes and the moisture

Even if you don’t plan to stay home, cold temperatures can cause water pipes to freeze and burst. A few practical habits can avert big headaches: let a small trickle run through taps on especially cold nights, open cabinet doors under sinks to let warmer room air circulate around plumbing, and keep a steady indoor temperature to discourage freezing. If you’re away for an extended period, have a friend or neighbor check on your property or consider turning the heating to a low, continuous level.

3. Prepare for travel disruption

Snow and ice can transform usual routes into slow crawls. If you must drive, allocate extra time, clear all ice from windows, and pack essentials in the car—blankets, a charged phone, a flashlight, water, snacks, and a first-aid kit. If the weather worsens, consider postponing nonessential trips and using public transport alerts or local travel updates to plan safer alternatives.

For those worried about heating systems failing due to extra demand, a power flush can improve boiler efficiency by removing sludge and improving water flow. Learn more from Powerflush about how a clean system can help maintain comfortable home temperatures during cold snaps.

4. Stock up on essentials

Snow days tend to shorten supermarket shelves. A small, practical reserve can reduce trips out in bad weather. Think bottled water, non-perishable foods, prescription medicines, and any daily necessities. If you live in a rural area, consider extra fuel, batteries, and a charger for devices. Being prepared keeps stress lower when travel becomes difficult.

5. Plan for school and work disruptions

Snow can lead to school closures or altered schedules. If you’re a parent or caregiver, have a quick plan for how you’ll manage a day at home with kids. If you’re an employee, staying flexible with remote work options can minimize disruption and keep workloads moving during a wintry spell.

Remember, when it comes to heat and comfort, Harrow Heating can be a helpful resource for staying warm during cold weather. And if you’re looking to optimize your heating system’s performance, Powerflush offers solutions to keep boilers and radiators circulating efficiently.

What to do if you lose power or heat

Winter weather can sometimes disrupt power supply. If the lights dim or you lose heat, safety first: stay warm with layers, use safe heat sources (never fuel indoors or close to flammable materials), and check on neighbors who might need help. If you rely on an electric or gas boiler for heat, keep some backup warmth options on hand—such as electric blankets or portable heaters that comply with safety guidelines. Don’t hesitate to contact your energy supplier for outage updates and estimated restoration times.

In the event of a prolonged outage, having a plan to relocate temporarily to a warmer space may be prudent, especially for the very young, the elderly, or anyone with medical needs. And for ongoing heating concerns, you can connect with professionals like Harrow Heating for guidance on staying comfortable even if you’re faced with a heater hiccup.

Preparing your home and family for a cold spell

Preparation isn’t glamorous, but it’s the best form of insurance for weather like this. A few targeted steps now can save you time, money, and stress later.

• Insulate exposed pipes and add pipe insulation in unheated spaces such as basements or garages.
• Keep a basic cold-weather kit: flashlight, extra batteries, a battery-powered radio, a small medical kit, and a well-stocked first-aid kit.
• Test smoke and carbon monoxide detectors and replace batteries if needed.
• Regularly check weather updates and travel advisories for your area.
• Arrange a plan with neighbors or family for sharing warmth, helps, or transportation if conditions worsen.

As you prepare, remember that a well-tuned heating system can make a big difference in how comfortable your home stays.
