A vortex is form when the whirling motion of the cloud vortex results from a rapid downdraft of cold air replacing rising hot air.

Rising convectively, a cumulus cloud is the most common.
A funnel cloud forms when the vortex of a developing tornado draws in moist air. As the air enters the vortex it undergoes a pressure drop, which in turn produce a temperature drop. This causes the moisture to condense and form a funnel cloud.

Rising hot air and water condensing out of that air.
The funnel cloud marks the location of a vortex where air spirals upward. This vortex formed from a larger vortex called mesocyclone, which was squeezed by a downdraft, causing it to tighten in diameter, intensify, and stretch vertically. This stretching causes it to extend downward.
The heat from condensation makes the rising air warmer and stay less dense than the air around it.
A tornadic vortex that is developing but has not yet reached the ground is called a funnel cloud.
