Cloudy weather makes photography more challenging but still it'll be worth a try, even for practise.
If possible you could try the following;
Set camera to Aperture mode (A mode)
Set aperature to around F6.2 (or there abouts),
ISO to 200,
Exposure compensation to +1/3,
Hopefully this will make sense, the instruction manual should be able to help find the various settings. I'm sure a few of the others can suggest some other settings as it's rare to see any two photographers using the same settings.
