The UK could be hit with a wall of snow and plunging temperatures following a mini-heatwave.

It comes after a balmy 20.1C was recorded at Kilnochewe the Scottish Highlands yesterday, according to the Met Office, the highest temperature recorded in the UK since 13 November 2022.

More opportunities to bask in the sunshine appear to be heading our way, as northern areas could again see temperatures in the high teens on Tuesday afternoon, including the Western Isles and some areas around the England-Scotland border.

However, an icy front is predicted to move in next week - with a return to cooler temperatures and even snow.

The wintery conditions are predicted to return thanks to a plume of bitterly cold sub-zero air pushing in from Scandinavia.

Weather maps predict this weekend is likely to be more unsettled, with most seeing a chance of some scattered showers and sunny spells.

However, showers could fall as snow over the Scottish Highlands, before wintery conditions move further south, bringing snow to higher ground in parts of northern England.

Overnight on Monday, the mercury is forecast to plunge to -4C in Scotland, -3C in the north east and will straddle 0C for the Midlands and the south east.

Wales and Northern Ireland will remain at around 2C before widespread showers for most on Tuesday, reports the Express.

Meanwhile Hay Fever sufferers have also been warned that elevated pollen levels are expect in many parts of the UK most of the week, as the first weeks of spring combine with mild weather conditions to spread airborne tree particles.

Allergy sufferers are likely to be affected in particular by particles from birch, plane, willow, ash and little oak trees, with April also being peak season for pleospora fungal spores.

A pollen forecast from the Met Office warns that pollen counts will be 'Very High' across all of Wales on Tuesday, as well as western areas of England and Scotland.

High pollen is also predicted across almost every other area of the UK mainland, with only Grampian at a 'Medium' level.

Yolanda Clewlow, the Met Office UK Pollen Forecast Manager, said: "We’re constantly monitoring what’s in the atmosphere and what might be coming, in terms of pollen in the air.

"Tree pollen is the main factor in the forecast at the moment, and this week, with more settled conditions, we’re expecting a large amount of birch pollen in the air, but these different types of tree pollen in the air will shift as we head towards summer."
