My guess is the clouds are reflecting the sound back to earth.

Speed of sound at relative humidity of 30% versus 80% (given constant temperature and presuure conditions) varies as 343.74 m/s to 344.37 m/s. So the sound from a distant point will travel faster to you on a humid day ( For a range 10 miles away, a gunshot sound will take .1 second less to reach you) but that does not necessarily mean that it should sound louder. The other explanation in the answers before is a better one. Clouds do reflect sound and the additional reflected sound waves will increase the effective volume of the sound heard making it 'louder'.

Cloudy days are indicative of increased relative humidity, therefore the air is more dense and transmits sound waves more efficiently.

the air is denser and transmits the sound waves better.
