UK Faces First Autumn Frost and Possible Snow as Met Office Issues Cold-Weather Warning
By Drooid · · How we work
Core Weather Outlook
The Met Office has warned that a surge of Arctic air will bring the season’s first frost and a “brief taste of winter” across parts of the United Kingdom. Wednesday night is expected to be the coldest night of autumn so far, with minimum temperatures in many towns and cities falling to just a degree or two above freezing by dawn on Thursday. A southerly shift in the jet stream will usher in northerly winds, delivering rain to England and Wales and raising the prospect of a temporary sprinkling of snow on the highest ground. The warning covers the period from Friday, October 9, through Monday, October 12.
Background & Context
September has been unusually warm, with daily highs above 20 °C in the south since June 11. The jet stream, which has lingered north of the British Isles, is now sinking southward, allowing colder air to flow in. At the same time, the ongoing El Niño event—record-strength in the Pacific—has been linked by some forecasters to an increased chance of wet, stormy autumn weather and, later, to possible disruptions of the polar vortex that could amplify winter cold. Other experts caution that the relationship between El Niño, the polar vortex, and UK snowfall remains uncertain.
Data & Statistics
- Temperatures: Wednesday afternoon highs of 12-14 °C in Northern Ireland and Scotland, 14-16 °C in England and Wales; Thursday dawn lows of 3-9 °C, with the coolest spots a degree or two above freezing.
- Rainfall: Southern and eastern England could receive 20-30 mm of rain—up to half a month’s average—in 24 hours, helping to alleviate drought conditions that still affect three-quarters of England and all of Wales.
- Wind: Maximum gusts of 37 mph are forecast for Friday, October 9; gusts drop to around 30 mph on Saturday, October 10, and to 20 mph on Sunday, October 11, before easing to 25 mph on Monday, October 12.
- Snow: Any snow is expected only on the highest ground, described as a “temporary sprinkling” rather than widespread accumulation.

Conflicting Reports & Gaps
Analyses of El Niño’s influence diverge. No definitive forecast currently links the present cold snap to El Niño-driven vortex changes.
