The UK is bracing for a dramatic shift as a late-season Arctic blast threatens to blanket the country in snow. Forecasters are warning of a massive 480-mile weather front that could bring disruptive conditions and temperatures as low as -9°C between April 3 and 5.
The recent spring warmth is set to vanish starting tomorrow. In its place, a biting winter chill will sweep down from the north, potentially creating a “blizzard” corridor stretching from the Scottish Highlands all the way to the south coast.
Timeline and impact areas for the Arctic blast
According to current forecast charts, the cold air will hit Scotland late on April 3, before migrating through northern England and the Midlands on April 4. By the early hours of April 5, the system is expected to reach the southern regions.
- Scotland & High Ground: Projected accumulations of 5-10cm, particularly in eastern areas.
- The Midlands & South: Lighter but potentially disruptive snowfall.
- Commuter Risks: Even in areas without heavy accumulation, a combination of sleet and freezing overnight temperatures will likely create treacherous, icy conditions on roads and pavements during the morning hours.
In their long-range forecast between March 30 and April 8, The Met Office said: “High pressure to the southwest of the UK will likely be the dominant feature for this period. This will lead to a fairly blocked pattern, with weather fronts rounding the high to affect northern parts at times, where wet and windy weather can be expected.
Further south, drier and more settled conditions are more likely, as frontal systems weaken as they meet the high pressure. Through the period, high pressure is likely to spread across much of the UK, leading to settled conditions developing more widely. Whilst temperatures will be generally near to or a little above average, some colder interludes are possible, especially in the north, where there could be some wintry showers at times.”
How cold will it get?
As skies clear behind the initial snow band during the Artctic blast, the mercury is expected to bottom out.
Scotland & Northern England – Down to -9°C (Rural), with highs of -2°C to -3°C
Southern England – lows of around 0°C
While southern regions may stay slightly warmer on paper, brisk northerly winds will create a significant wind chill, making it feel much colder than the actual temperature. Temporary snow cover is predicted to reach as far as the English Channel before the weather transitions to more unsettled, changeable patterns heading into the second week of April.
