last summer i video'd several cold air funnels from my balcony. they really looked like tornados. there was several one after another. funny thats where they were seen a few yrs ago. maybe terrain part of the factor. anyways i was shocked to hear tornados on the scanner. looked at the radar and was like there wasn't even a storm on there!!!! that's how you tell a cold air funnel from a tornado. if it was a tornado there would be some scary stuff on radar. funny thing is our town went ahead and sounded the sirens. everyone in this county and adjacent was freaking out at first.I keep hearing people talk about "cold air funnels." Rotating funnel clouds that won't ever touch down. Any truth to that?
