I’m saving the chance is lower than several days ago for the.first two system (it’s still a chance) , no shit there is a chance at this range . You know when you click on your weather app and it says 70% chance of showers later tonite and then you click 6 hours later and the chance has gone to 50% , that is the idea here for the 9-15’th period . It doesn’t require a degree in meteorology or mathematics but perhaps psychology
