A broad westerly regime will dominate during Saturday across the British Isles, with subtle shortwaves helping to generate areas of enhanced convective activity. The pattern is quite complex, with NWP guidance offering slightly different forecast evolutions - and hence uncertainty is quite high in the specific detail.
Nonetheless, weak instability in a strongly-sheared environment suggests isolated lightning strikes may be possible as various convective / semi-convective features move quickly eastwards in the strong steering flow. Strong gusts of wind remain possible associated with areas of enhanced convective activity.
