Yesterday evening, while visiting with a friend and waiting for dinner to be ready, we noticed these bizarre looking funnel clouds forming. They looked like cute, skinny tornadoes (bet you never heard a tornado referred to as "cute"), but they never touched the ground and there was no severe storm involved. Some did get pretty long before dissipating, some were even horizontal. We saw...I don't know...maybe six or seven of them (?) over the course of about 45 minutes.
Here's what a short video from a local news station:
And you can
link here to see what another local station had to say. And you can
go here for some pretty impressive pictures of other cold air funnels. :)
"Cold-air funnel clouds (vortices) are usually short-lived and generally much weaker than the vortices produced by supercells. Although cold-air funnels rarely make ground contact, they may touch down briefly and become weak tornadoes or waterspouts.

A shear funnel extending from a generic cumulus cloud. Observed in northern
Texas by a member of the
VORTEX project.
Unlike the related phenomenon associated with severe thunderstorms, cold-air funnels are generally associated with partly cloudy skies in the wake of
cold fronts, where atmospheric instability and moisture is sufficient to support towering
cumulus clouds but not precipitation. The mixing of cooler air in the lower
troposphere with air flowing in a different direction in the middle troposphere causes the rotation on a horizontal axis, which, when deflected vertically by atmospheric conditions, can become a funnel cloud.

They are a common sight along the Pacific Coast of the United States, particularly in the spring or autumn."
Pretty cool!
