I just installed the openweather binding to switch from Darksky due to the Apple acquisition and I found in the documentation that it is possible with the free api to get a forecast for 120 hours equals 5 days.

The openweathermap binding will also pull the coordinates from your OH system settings (Configuration> System> Regional Settings).
