¿Which is the difference between cloudy and foggy?

Cloudy is for the sky, for example and foggy it's a normal form how, The street 45 is very foggy now. for example

Cloudy: "It's about to rain cats and dogs" Foggy: "I can't see a sh***"

It's an awesome explanation, thanks for your answer.

Hey Yosef,

We could say

Foggy is a weather where there's mist and it's hard to see because the clouds are lower to the ground.

For example, higher up on the road to the mountain it is foggy.

Cloudy means there's a lot of clouds in the sky; it's not that sunny outside.
