Heavy snow was affecting Colorado, Nebraska and parts of Iowa early Wednesday. More than 300 flights were already canceled as at 6 a.m. ET, FlightAware reported, with Denver, Colorado, the hardest-hit airport.

The powerful weather system has already delivered record-setting snowfall in Colorado and triggered 3,400 lightning strikes across Arizona early Monday.

Minneapolis was forecast to see between 5-8 inches of snow Tuesday, with 11 inches forecast for Omaha, 12-18 inches for Sioux City, Iowa, and "about a foot" across Wisconsin, Roth said.

Thunder and lightning was possible amid the snowfall in parts of Nebraska and Iowa.

Even in areas where snowfall has stopped, such as central Nebraska and northwest Kansas, strong winds gusting up to 60 mph were likely to blow the fallen snow around, leading to ground blizzards.

"That will reduce visibility to very poor, with dangerous driving conditions," Roth said. "In white-out conditions you won't be able to see very far in front of you, if at all."

However, the storm is likely to wind down by the end of Wednesday.
