BRITS can struggle with a snowstorm as early as next month, with temperatures expected to fall.
Predictors say a bitter cold could blow up Britain as an Atlantic change of weather moves across the country.
Uncovered weather is expected to hit the country with wild conditions in late October – potentially covering some areas in a blanket of snow.
From October 20, the wettest and windiest conditions will remain in the north and northwest, while things will be more settled in the east and south.
Drying will continue until the last week of October, possibly creating a white Halloween.
According to the Met Office, the colder settlement period will be set in early November.
The Met Office previously warned that temperatures in some areas could plummet by 10C in weeks.
Former BBC weatherman and meteorologist for Weather Trend John Hammond told The Sun: “There are signs that the stratosphere is experiencing unusual warming over the next few days, causing the polar vortex over the Arctic Circle to become less strong than usual later in October.
“These wind heights are usually intensified as we approach winter. So an unusual weakening of the polar vortex may very well affect our weather later in the fall and into the early winter.
” Sudden stratospheric warming ‘events can sometimes cause the polar vortex to reverse, which can have dramatic effects on winter weather and increase the chances of severe cold.
“However, there are as yet no indications that such a turnaround will occur.
“The last time the lowlands of southern Britain saw significant snowfall as early as October was in 2008 – a measure of how rare it is.”
Met Office chairman Marco Petagna added that the weakening of the polar vortex could “have consequences for our weather into the winter”.
The snow forecast is bad news for families hoping to get out in the half term – which runs from Friday 22 October to Monday 1 November.
Met Office press officer Stephen Dixon added: “There is a north and south split this week, with the southern areas remaining largely fine, with dry conditions, good sunshine periods and heat.
“The lion’s share of the unresolved conditions are in the northern parts of England, which can expect a chance of frost and uneven rain.
“There are altitudes this week of 18 degrees Celsius, which is more likely in the south of England and Wales.
“There is a high-pressure system in the western part of the UK, and our long-distance weather forecast has shown that uneasy conditions will move in from next week.
“In rural Scotland, you can expect to see a chance of frost with night temperatures likely to be minus.”
The expected cold comes after September was the second warmest on record for Britain, with Northern Ireland having its joint warmest September on record.
CHOST OF FROST
Scotland had its second warmest, Wales the third and England the joint third, according to preliminary figures released by the Met Office.
Temperatures were 0.05C warmer globally than in the same period last year.
It was also the warmest September Europe has seen, beating the previous record in 2018 by around 0.2C.
Temperatures were above average in other regions of the world, including the Middle East, parts of South America and Australia.
And the EU’s Copernicus Climate Change Service (C3S) said the Siberian Arctic remained warmer than average.
Last month, Arctic sea ice covered the smallest area since 2012.
