After a brief taste of spring sunshine, both the UK and Ireland are bracing for a sharp return to wintry conditions, with forecasters warning of snow, sleet, biting winds, and a dramatic drop in temperatures across the British Isles in the coming days. Weather maps, expert predictions, and official forecasts all point to a turbulent week ahead, as a cold north-westerly airflow sweeps across the region, bringing a mix of heavy rain, blustery winds, and, for some, significant snowfall.
According to WXCHARTS weather maps cited by The Express, the first signs of the cold snap will arrive as early as Monday, March 23, 2026, when Aberdeen in Scotland is expected to see snowfall, making it the first city to feel the chill. But this is only the beginning. By Tuesday, March 24, snow will be spreading across western parts of the UK, particularly targeting Scotland, Blackpool, and Wales. The wintry weather won’t stop there: by Wednesday, March 25, the snow is forecast to move east and south, reaching as far as Plymouth and Norwich, and blanketing much of northern Scotland, the north-east and north-west coastlines of England, and even parts of Wales and Northern Ireland.
The heaviest snowfall is expected in Scotland, with the snow depth chart indicating that Gairloch could see accumulations of up to 14 centimeters. By 9 a.m. on Wednesday, regions north of Dundee are predicted to be fully covered in snow, while in Wales, the western coastline and inland areas toward Cardiff will also receive substantial snowfall. England’s Cumbria, Manchester, and Stoke-on-Trent are in line for snow Wednesday morning, and by 9 p.m., the eastern coastline from Newcastle to Ipswich is expected to see flurries as well. The Midlands and southern England, however, are likely to remain mostly dry, with only isolated patches of rain or snow that aren’t expected to stick around. Northern Ireland will escape the brunt of the wintry blast, with only a limited area near Derry forecast to see any snow at all.
The Met Office’s five-day outlook, as reported by The Express, paints a picture of overcast and breezy conditions in the north on Sunday evening, with fog patches forming elsewhere. Their forecast for Sunday, March 22, calls for scattered rain moving southeast across the UK, followed by sunshine in southern England after a foggy start. The northwest will turn brighter and colder, with some blustery showers. For the start of the week, the Met Office predicts, “Turning wet and windy in the north on Monday. Elsewhere fog clearing, then bright spells. Rain clearing southeastwards on Tuesday. Cold and windy midweek with sunshine and showers, some wintry.”
Steve Willington, the Met Office’s Chief Forecaster, offered some context for the sudden shift, saying, “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 we head into next week, a shift to a cooler north-westerly flow will bring a drop in temperature and more unsettled weather, including some hill snow in the north and brisk winds at times. This pattern is entirely typical for the time of year.”
Indeed, the temperature drop will be noticeable. After a weekend that saw the mercury reach the mid to high teens, midweek temperatures are expected to return to more seasonal averages, or even dip below them. Windy conditions will be particularly pronounced across northern regions, with the Met Office warning of brisk winds and, on the coasts, the risk of gales. By Wednesday, the UK will be firmly in the grip of a cool, unstable north-to-north-westerly flow, bringing frequent showers—some heavy and wintry, especially over higher ground. There’s even a possibility that snow could reach lower levels in the north later in the day, with overnight frosts likely as the week wears on. Toward the end of the week, higher pressure is expected to build from the west, reducing showers and easing winds, but temperatures are likely to remain on the cool side, with the chance of more frosty nights.
Ireland is not immune to the coming wintry blast. As reported by the Irish Mirror, the country enjoyed its hottest day of the year so far on Friday, March 20, 2026, with temperatures peaking at 18°C. But that warmth is about to vanish. Alan O’Reilly, a leading meteorologist at Carlow Weather, warned that it’s time to “take the big coat back out of storage,” as temperatures are set to plummet below freezing and heavy rain, sleet, and snow are forecast for the week ahead. O’Reilly explained, “It is going to change next week, so Monday will stay largely dry, but there could be a few little patches of drizzle here and there, with some sunny spells as well. Tuesday then will turn wet though, so we will see rain on Tuesday and a risk of some heavy rain, actually, on Tuesday, moving south across the country. It will also turn much cooler then from Wednesday. So… the wind is going to go northerly, and it’s going to pick up as well, so it’s going to feel much, much cooler. So if you did put away the big coat you’re gonna have to take it back out, I’m afraid.”
Met Éireann’s national outlook lines up with O’Reilly’s warnings. Sunday, March 22, will start cloudy and misty, with scattered light rain and drizzle, clearing southeastwards later to reveal sunny spells from the northwest. Monday will be mostly dry, but patchy rain and drizzle will arrive by the afternoon, extending further southeast into the evening. Monday night will turn breezy, with outbreaks of rain and drizzle spreading southeast. Tuesday will bring blustery conditions, with sunny spells and widespread showers, some heavy and possibly accompanied by hail or thunder. The real chill sets in Tuesday night, with blustery winds and scattered showers—some of sleet and snow—as temperatures drop to 0°C in places. Wednesday will be a windy, cold day, with sunny spells and scattered showers, some wintry, especially in the morning. Daytime highs will only reach 6°C to 9°C, and strong northwesterly winds will make it feel even colder. The outlook for Friday and the following weekend remains unsettled, with mixed conditions expected to persist.
For many, this abrupt transition from spring warmth to wintry weather will come as an unpleasant surprise—especially after such a promising start to the season. The return of overnight frosts, gusty winds, and the prospect of snow and sleet will be a reminder that March is, as ever, a month of meteorological mood swings. While the heaviest snowfall is expected to be confined to high ground in the north and Scotland, even lower-lying areas could see wintry showers, particularly as the week progresses. Those in southern England and much of the Midlands can expect to escape the worst, but should still be prepared for colder, unsettled conditions.
As the week unfolds, all eyes will be on the shifting weather patterns and the potential for disruption, especially in areas where snow is forecast to accumulate. For now, it seems the best advice is to keep that winter coat handy and brace for a few more days of classic British and Irish weather—unpredictable, dramatic, and never dull.
