They say these are cold air funnels.
It looked like it touched the ground to me.
what the heck are these things anyway?
Cold air funnels are exactly what the name says... they are funnels. As low pressure systems with colder than normal air move across The Plains..the change in winds at different altitudes can cause funnels to drop out of clouds. The important thing to note here is that the winds within these funnels up high are hardly that strong. Cold air funnels typically have winds under 55 miles per hour in them.
Most never touch the ground.
What makes these challenging to forecast is that they can be produced out of simple rain showers. That's right.. no lightning..no thunder..no hail or even strong winds. Simple rain showers can produce these.
The NWS will never issue a Tornado Warning for these because A) They are impossible to detect on radar and B) They tend to only last a few minutes and hardly ever come close enough to making contact with the ground.
So how should you treat these? Treat them like you would any funnel. Stay away from them. In the very small chance that they do make contact with the ground..then they can produce damage similar to an EF0 tornado.
