Clouds with the prefix of 'alto' are middle level clouds between 6500 and 23,000 feet. The two alto clouds are altocumulus and altostratus and these types of clouds usually bring precipitation from rain.
Stratocumulus clouds brings very little precipitation but they can bring light drizzle or a tad bit of snow.
They look like a huge gray blanket that hangs low in the sky. Sometimes stratus clouds are on the ground or very near the ground, and then we call them fog.
You get no precipitation from cirrus clouds, they are too thin and too high. Hence, the weather they bring is dry.
All tornadoes are produced by thunderstorms.
