Some 55 million people are under threat of severe weather as the atmosphere recharges Saturday, stretching some 1,500 miles from border to border along the Plains, Mississippi Valley and into the Great Lakes, including many of the places still picking up the damage from Friday’s storms.

Both the Omaha, Nebraska, and Minden, Iowa areas that took direct hits from tornadoes on Friday are under a Level 2 severe weather risk on Saturday.

HOW DOES A TORNADO OUTBREAK HAPPEN?

The severe risk reaches north into the Great Lakes, encompassing swaths of Michigan, Illinois and southern Wisconsin, including Milwaukee, which are also under a Level 2 risk on Saturday.

More daunting weather news: Flash flooding likely in severe weather outbreak zone

If tornadoes, hail and wind were not enough, much of the Southern Plains is also at a significant risk of flash flooding Saturday into Saturday night.

As the severe thunderstorms become more widespread on Saturday evening, some will be capable of producing heavy rain at the rate of 2-3 inches per hour. 

Thunderstorms may be slow movers or stall, allowing multiple inches of rain to fall on the same areas, leading to significant flooding issues.

WHAT ARE TRAINING THUNDERSTORMS, AND WHY ARE THEY SO DANGEROUS?

NOAA’s Weather Prediction Center has a Level 3 out of 4 flash flood risk stretching from northern Texas through the heart of Oklahoma, including Oklahoma City, into southeastern Kansas and southwestern Missouri.

No rest for the weary: More severe weather expected Sunday
