It's a funnel cloud, but it is not associated with a thunderstorm. You often see these associated with intense areas of low pressure and very cold air aloft. These conditions duplicate the very turbulent conditions of a tornadic thunderstorm, but on a much larger and thus weaker scale.
These rarely touchdown, but if they do...they are considered to be a tornado and can do some light damage.

A cold air funnel is a high base weak tornado that is formed high above the earth in a shallow cold air mass. They rarely cause problems as they are high above the surface of the earth. They are visible when the middle and lower troposphere are moist have substantial winds and are flowing in directions opposite to each other.
