As I said you need to use the accuweathercore for this (that supports up to 15 days data)
The ${......}1 tags are for today, ${......}2 for tomorrow.. etc
So for example for your "In 3 days: dd/mm" you have all these tags to choose from depending of what you want

${dayNumb03}/${month3}
PM: Maybe there is a way through java script code to visualise more dates but I don't know the form.
But 15 days are enough I think..
