UK Weather Set for Sudden Shift as Snow Approaches

As the UK basks in a warm and settled weekend, a stark change in weather is on the horizon. Following a week of sunshine that brought the warmest day of the year so far, temperatures are set to drop significantly, with snow expected in various regions of the country.

On Friday, March 20, 2026, much of the UK will enjoy pleasant weather, with temperatures climbing into the mid to high teens. Major cities such as Manchester and Edinburgh are forecast to reach 16°C and 15°C respectively, while Bristol and London are looking at highs of 15°C and 14°C over the weekend. The Met Office attributes this warm spell to high pressure dominating the weather, creating ideal conditions for outdoor activities.

However, this blissful weather is not expected to last. From Sunday, a weakening band of cloud and patchy rain will push southeast across the UK, followed by sunny spells and scattered showers in the north. Some of these showers may turn wintry, particularly over higher ground. Met Office Chief Forecaster Steve Willington remarked, “While the early part of the period brings warm sunshine for many, it’s not unusual to see colder spells and even some wintry showers in March.”

As the week progresses, a shift to a cooler north-westerly flow will bring a drop in temperature and more unsettled weather, including hill snow in the north and brisk winds at times. Rain is expected to spread into northern and western areas on Monday and Tuesday, occasionally turning to snow over the Scottish mountains. By Wednesday, the UK will experience a cooler and more unstable north-to-north-westerly flow, with frequent showers, some heavy and wintry over higher ground. Snow could even reach lower levels in the north later in the day, leading to a significant change from the recent warmth.

Temperatures are forecast to hover around or slightly below average, with some areas experiencing overnight frost. The Met Office has warned that the cold plunge is likely to be felt most acutely by Wednesday night, when temperatures could drop to single digits in many areas.

The contrast between the recent warm weather and the impending cold snap is striking. Just days earlier, on March 18, Scotland recorded its warmest day of the year with temperatures peaking at 20.9°C in Goggerdan, Wales. This sudden transition to wintry conditions has left many residents surprised, as they prepare for what feels like a shock to the system after enjoying sunny days.

Looking ahead, weather maps indicate that snow could hit several major UK cities next week, including Glasgow, Blackpool, Manchester, Birmingham, and possibly even London. Some areas might see temperatures plunge as low as -6°C, while Glasgow and Newcastle are expected to hover around -3°C. The snowfall is projected to arrive in Scotland, Northern Ireland, and northern England during the early hours of March 27, with conditions pushing southwards throughout the day.

Forecast models suggest that by midday on March 27, cities like London, Birmingham, Norwich, Nottingham, and Manchester could also be affected by the wintry weather. In some parts of western Scotland, snowfall could accumulate up to 18 cm, posing challenges for transportation and daily life.

Despite the fluctuating weather patterns, the Met Office assures that the rain and wind are expected to ease later in the week. However, even as high pressure builds from the west, cooler temperatures are likely to persist, with continued risks of overnight frost.

For those who have enjoyed the recent warmth, this upcoming cold snap may feel particularly jarring. As Willington noted, “This pattern is entirely typical for the time of year.” March is known for its unpredictable weather, and this year is no exception.

As the UK transitions from a warm weekend into a week of potential snowfall, residents are advised to stay updated with the latest forecasts. The Met Office provides continuous updates through various channels, including their website, YouTube, and social media platforms. With the weather changing so rapidly, it’s crucial to be prepared for whatever comes next.

In summary, while the weekend offers a brief respite of warmth and sunshine, the forecast for next week suggests a return to winter conditions. As the nation braces for snow and colder temperatures, the Met Office's warnings remind everyone that spring can still be unpredictable.
