Look at the large white cloud over France, that's a Mesoscale Convective System (MCS), a huge storm system which is currently moving N towards the UK with another further W which will track up through Ireland. It might make land fall during the early morning hours and move across the country. Thurs can go either one of two ways, the first is a non event with just heavy rainfall, the second being a spectacular storm event, possibly the best since 2005/6. Time will tell, although I'm only expecting rain here tommorow, anything sparks would be a bonus.
