The Met Office has said no snow is currently expected in the UK between October 9 and November 2, even as forecasters warn that an 'enormous' El Niño could bring an icy winter later in the season.
El Niño's global impact
According to meteorologists, the El Niño weather phenomenon will continue to affect global conditions in the coming months. The Met Office has warned that this extraordinary climate pattern, which has already played a major role in driving temperatures to record-breaking summer highs, is expected to keep influencing weather systems worldwide. Forecasters said its effects are likely to be widespread, with significant consequences for weather conditions across the globe.
Polar vortex disruption risk
Experts are predicting a wet and stormy autumn that could develop into an icy winter. Professor Adam Scaife, head of long-range predictions at the Met Office, said: "We have been signalling for months that the developing El Niño will be an unprecedented event."
"The fact that it has already exceeded previous records – with several weeks to go before it peaks later this year – shows the enormity of this El Niño. Scientists are still assessing whether the impacts will be in proportion to its magnitude, but we are already seeing expected effects worldwide."
Forecasters have warned that the climate phenomenon could interfere with the stratospheric polar vortex, a vast band of powerful cold winds circulating high above the Arctic. Any significant disruption to this system has the potential to weaken the jet stream, allowing frigid Arctic air to spill southwards into parts of Europe and North America, bringing a heightened risk of severe winter weather.
Short-term outlook
However, experts say such an event would be more likely to influence conditions later in the season rather than during autumn. As a result, the chances of a polar vortex-driven cold snap affecting the UK in the coming weeks remain relatively low, reports the Independent.
Separately, the Met Office has given its verdict on snow in the shorter term. None is currently expected between October 9 and November 2. Its forecast reads: "It will be a changeable period as weather systems move in from the Atlantic, bringing spells of rain or showers to most areas. There will be heavy at times, especially in the northwest, with some strong winds. There will still be some drier and brighter interludes between systems, especially in parts of the south and east. Temperatures will likely be near to normal at first, perhaps becoming warmer later."
"Late October into early November will probably maintain a changeable pattern overall with weather systems often moving in from the Atlantic. These will bring showers or longer spells of rain at times, with the wettest and windiest weather in the northwest, drier in the southeast. There is a chance that a period of more widely dry conditions could develop for a time, but confidence in the details of this is low. Temperatures will probably be above average overall."
