What is a cold air funnel?May 16th, 2014 at 4:45 pm by Robb Ellis under Weather
The possibility of cold air funnels this afternoon may lead you to wonder what a cold air funnel is. This is not your typical funnel that produces a tornado.
In fact, the National Weather Service does not issue a tornado warning for cold air funnels because they rarely touch down, and are usually extremely brief.
They are also almost impossible to detect on a radar.
These funnels form from the colder air in the upper levels in the atmosphere.
If a cold air funnel happened to touch ground, it would produce winds similar to a weak tornado. So it would not be a bad idea to get to a safe part of your home just for caution.
