## Key points

- Dry weather is the professor’s main concern.
- Reservoirs may not refill over winter.
- Snow is currently considered unlikely.

## Summary

Professor Andrew Charlton-Perez says the main UK concern from an unusually early weakening of the polar vortex is prolonged dry weather, rather than snow. With parts of England and Wales still in drought after a record hot, dry summer, further lack of rain could prevent reservoirs from recovering and threaten water supplies next summer.

The weakening is linked to sudden stratospheric warming, which can shift the jet stream and bring more settled, colder and drier conditions. Charlton-Perez said records show no earlier event than very late November, and that snow is currently unlikely because heat remains in the oceans, land and atmosphere. Some areas need more than 120% of their usual monthly rainfall through winter to end drought.
