Wouldn't worry about these precipitation charts yet,from my experience little features pop up out of nowhere nearer the time, so will be plenty of surprises I'm sure. Can always remember one around 2009 or 10 where there was a small area of snow sitting off the coast circling on the rain today radar one Sunday afternoon, it then moved inland and give Stamford Bridge(where I was at the time) a right dumping for a couple of hours. Wasn't forecasted either! Good luck guys ???
