WXCharts' UK weather maps warn of two Arctic air masses set to impact the country across the week, which could lead to snowfalls of around one centimetre per hour.
A Warm Easter Sunday
Over Easter Sunday, temperatures reached ten degrees Celsius in some parts of south-east England. In Wiggonholt, West Sussex, the temperature even reached 18 degrees Celsius. For many people, this was a welcome change, as they were able to enjoy the outdoors and take part in the Easter festivities.
Even in northern parts of the UK, such as Auchincruive in South Ayrshire, temperatures were a pleasant 16 degrees Celsius. However, anyone familiar with the British climate will tell you that these conditions are not likely to last.
This week, two Arctic air masses are expected to hit the region. A sudden change in the weather is expected to begin on Wednesday, with temperatures dropping as low as 3 degrees Celsius across the UK.
Among the areas expected to be most affected are parts of Cumbria, Lancashire, West Yorkshire, East Yorkshire, North Yorkshire, County Durham and Northumbria in England, as well as parts of Scotland.
Snowfall Predictions
As far as weather analysts are aware, snow could start falling as early as Wednesday evening painting the summits white at altitudes of 900 to 1,000 metres, dropping to 500 metres as the night progresses. The heaviest snow showers of around an inch per hour expected for Northumbria and County Durham.
By Friday morning, these same areas, as well as areas further north such as the Scottish Borders and Ayrshire, are expected to receive even heavier snowfalls. But the plot thickens, as the day promises a north-south split, with the northern regions preparing for further rain, while the southern regions can look forward to a little respite thanks to clear spells and moments of sunshine.
Temperatures will also be evenly distributed, with the south enjoying warmer periods of sunshine, with temperatures reaching 15-16°C. On the other hand, rainy areas will be considerably cooler, and even the most northerly parts of Scotland, although drier, will have to contend with biting winds.
The potential accumulation rates could exceed 5 centimetres per hour by 9am in East Ayrshire, the Scottish Borders and higher areas of Cumbria.
A Wet Evening Ahead
As dusk approaches, incessant rain will soak many parts of eastern Scotland. This phenomenon is being triggered by a low-pressure centre which is bringing with it a weather system from the south-west.
However, there is a brief interlude of drier weather in parts of Northern Ireland and Northern England before the rain arrives. Rest assured, this set promises to deliver a powerful performance.
Met Office Long Range Weather Forecast : Sunday 7 Apr–Tuesday 16 Apr
Looking at the weather forecasts for the coming weeks, we can expect unstable conditions to persist, with little indication of any significant changes. Rain showers or periods of rain can be expected at times in all locations, with heavier rainfall in the western hill areas.
Flighty winds are likely early in the period, and further windy spells are likely until mid-April. Even though unstable weather is most likely, some areas may experience brief dry interludes.
However, any interruption in rainfall is likely to be short-lived and, up until next week, the best chances of slightly drier conditions are in the southern regions.
Temperatures above normal are very likely overall, although at times moderated by cloud cover, rain and occasional strong winds.
