UK snow forecast as long-range weather maps show early frost: ‘Prepare for the worst’ | Weather | New
Weather experts have urged to ‘prepare for the worst’ as cold weather weather drivers join forces for a cocktail of winter misery. A La Nina cooling of the eastern Pacific, sudden stratospheric warming of the Arctic (SSW), which chased the 2018 beast from the East, and tenacious high pressure threaten to drive cold weather as early as November.
Temperatures are forecast to threaten to plunge early next month as winter storms begin to intensify.
James Madden of Exacta Weather said: “La Nina may bolster the opportunity for cooler shots during the latter part of fall, and current indications suggest a cool November is on the cards.
“We expect stormy conditions throughout November, which could coincide with colder incursions to produce early winter outbursts.
“There is now a very strong chance that La Nina will continue through the fall and winter of 2022/23.”
Scotland and the north of England will be first in the line of fire for the cold, which could arrive as early as this month, he added.
The frost forecast comes as the Met Office warns early signals point to a cold spell at the start of winter.
Depending on how high pressures build over the next few weeks, Britain could find itself in the path of a torrent of northerly winds.
An SSW event, which occurs when cold air in the Arctic stratosphere descends, causing temperatures to rise, can shake up the jet stream and open the gates to freezing easterly winds.
Such a scenario was the driving force behind the prolonged extreme cold and snowfall in late winter, early spring 2018.
Met Office chief meteorologist Paul Davies said: ‘Exact weather conditions will be dictated by where the high pressure settles over the Atlantic and the UK.
“But we are likely to see a higher incidence of airflow from the north, preventing mild, moist air from flowing into the UK from the Atlantic Ocean and increasing the potential for cold snaps with some threat. snow and ice, mainly in the northern regions.
“The most likely scenario as we approach 2023 is a decrease in the risk of high pressure and a return to more unstable conditions with possible wet, windy and mild spells.
“However, there is always a risk that we could see sudden stratospheric warming.
“If that happens, it could potentially lead to a cold snap for the UK and Northern Europe.”
However, the chances of a very cold winter comparable to the cooler 2009/10, he said, are low.
Independent forecasters agree the outlook is still uncertain, though they warn to prepare for the worst.
Jim Dale, meteorologist for British Weather Services and author of Weather Or Not? said: “We have a strong La Nina and that was the driving force behind the very cold winter of 2009/10.
“However, while there is no certainty that will be the case this year, it is important that people prepare for the worst as it is very possible that we are heading into a cold period.
“In the event of a harsh winter, it is crucial to be prepared, especially this year with the energy crisis and the cost of living.
“It’s about preparing for a possible worst-case scenario, but hoping that doesn’t happen.”
The frosty predictions prompted bookies to start cutting the odds of festive snow with Coral offering 4-5 from 2-1 on a White Christmas.
Spokesman John Hill said: “We are less than 100 days away from Christmas now, and with temperatures set to drop rapidly over the next few days, early odds suggest we could be ready for a White Christmas this year. .
“Not only have we reduced the chances of October ending as the coldest on record, but we’re not ruling out snowfall.”
