Cold-air funnel clouds are not uncommon with the current weather pattern in the state, the NWS said.

PHOENIX — Residents across the Valley on Monday were surprised to see what looked like a funnel cloud hanging from the sky. 

The National Weather Service confirmed it was a cold-air funnel cloud. The NWS said they received reports of the clouds near Tucson and in the Phoenix metro area. 

The cold-air funnel clouds are not uncommon with the current weather pattern in the state, the NWS said. But the atmosphere doesn’t have all the ingredients to produce a full tornado.

What’s a cold-air funnel?

Cold-air funnels form beneath showers or weak thunderstorms when the air aloft is especially cold, the NSW says. 

The funnels are most common in the fall and spring when the sun is able to heat up the lower levels of the atmosphere, causing convection to bubble up and form showers, but temperatures around 15,000 to 20,000 feet above the ground are quite cold.  Cold air funnels are usually harmless, but on rare occasions, they can touch down and cause EF-0 level (winds up to 85 mph) tornado damage.

There were several reports of a funnel cloud in the north Valley Monday. It turns out it was a cold-air funnel.
