What is drizzle?

Drizzle is nothing more than very small raindrops. It usually occurs when updrafts in clouds are weak, and the clouds have bases close to the ground (less than 1,000 feet high). Fog is often present when drizzle falls. Drizzle drops grow as cloud droplets collide and combine with each other, but then fall out of the bottom of the cloud before thay can grow into bigger raindrops.

Interesting facts:

FREEZING DRIZZLE: In the wintertime, a very shallow surface layer of very cold air can exist with a much warmer layer of air over it. Drizzle can form in the low clouds that mark the boundary between the warm and cold air, and can fall to the surface before they have a chance to freeze into snow. Freezing drizzle can occur at surface temperatures as low as 10 degree F, or even lower.
