No it does not. A dark cloud, (or maybe a few) doesn't ever automatically mean a thunderstorm is coming. (plus it usually rains a little first)
A dark cloud may be caused by the angle of light or the background contrast of the sky behind the cloud(s)
With no stars it's clouded
With stars it's clear sky

an educated guess
A dark rain cloud is called a nimbus. These clouds produce rain and snow as they are filled with compact and frozen moisture.
white clouds seldom give rain; grey clouds are more potent to give rain which is why the sky is usually grey or dark grey when it rains :)
rain falls of the sky snow falls of the sky
observation
no it will not rain because when you see the clouds/sky blue and the sun it means it will not rain, but when the clouds get dark that means maybe it will rain.
an educated guess
yes. if its about to rain, it will be a dark ocean. if it is sunny, it will be a regular...
Today I noticed the dark clouds in the sky, and I decided not to take our dogs out for a walk, for fear of rain.
Why dose the sky get dark what is the sighn
No, because some times when there are dark clouds its still warm or humid whenever it might rain.

If it is sunny after the rain has stopped, you are likely to see a rainbow in the sky.
