Storm clouds fill the sky north of Zumbrota off of 190th Avenue Monday afternoon. The National Weather Service conditions were right Monday for cold air funnel clouds, which are not as destructive as tornadoes.

As the cool start to June continues into the third week of the month, cold air funnels made a visit to the region Monday.

Atmospheric conditions were just right for formation of the meteorological phenomenon, National Weather Service officials in La Crosse, Wis., said Monday.

Warm air mixing along a frontal boundary along with condensation can cause rotation and clouds that can resemble tornadoes.

“It’s kind of a unique setup that gets these things in motion,” said NWS meteorologist David Schmidt.

While they do have strong winds, cold air funnels do not have the same destructive potential as tornadoes and don’t usually touch the ground.

“Typically, these aren’t the damaging kind of funnels,” Schmidt said.

That said, they can pack winds of up to 85 mph, break tree limbs and toss debris.

“If you do see one, you should stay away,” Schmidt said.
