Polar Vortex Disruption: UK Cold Spell Unlikely Soon
7 Oct
Summary
- El Niño may weaken stratospheric polar vortex, but impact on UK is uncertain.
- Experts say a polar vortex-driven cold spell in the UK is unlikely soon.
- Near-term cold spell and snow predictions for the UK are currently unfounded.
The potential impact of El Niño on the stratospheric polar vortex and subsequent cold weather in the UK remains uncertain. While El Niño can sometimes weaken the vortex, meteorologists indicate it is too early to determine if this will cause frigid air to move further south into the UK this autumn or winter.
Experts caution that any influence on the polar vortex is more likely to manifest later in the winter rather than during the autumn months. Therefore, the prospect of a cold spell driven by the polar vortex affecting the UK in the near term is considered relatively low. Forecasters have also stated that suggestions of snow due to this weather event are currently unfounded.
The Met Office's long-range forecast indicates a changeable pattern for the UK through mid-October and into early November. This suggests a mix of rain and wind, interspersed with brighter, showery conditions, particularly in the west and northwest, with drier conditions more favored in the east. Temperatures are generally expected to be near or slightly above average for the period.
