This kind of precipitation is called sleet. It bounces when it hits the ground. If snowflakes completely melt in the warmer air, but temperatures are below freezing near the ground, rain may freeze on contact with the ground or the streets.

When clouds develop or precipitation occurs, something is making the air rise. When air rises it expands and gets colder and since colder air cannot hold as much moisture as warm air, the water condenses to form clouds and sometimes rain or ice or snow!

These droplets are way too small to fall as precipitation, but they are large enough to form visible clouds. Water is continually evaporating and condensing in the sky. If you look closely at a cloud you can see some parts disappearing (evaporating) while other parts are growing (condensation).
