Look at the precipitation to the north west of France. That is our best chance! Don't give up yet! It is not even going to reach us until midnight so hold on :-) I am just talking about Sussex eastwards
My prediction is all the energy being released later than Saturday. Probably into Sunday with it initiating further East as the cold Front moves in. I would delay the front by 12 hours
Looks as though it will just be mostly rain with a few rumbles. The storm is only at the back of the one off the SE and hasn't moved. Just rain moving in now
