Looking at SpaceWeather.com today I see that NASA has estimated a 90% chance of geomagnetic storms tonight. The speed of the solar wind around Earth could peak at 1.6 million mph compressing the Earth's magnetosphere. Given a clear sky an aurora might be seen from northern parts of the UK. I have seen one photo of a faint aurora which was taken in Scotland within the past week.
Unfortunately it looks as though many areas will be under cloud cover as shown in a tweet from AuroraWatchUK.
