Days earlier, the same ferocious weather system spawned violent twisters, blinding dust storms and fast-moving wildfires, leaving at least 39 people dead in the South and lower Midwest. Here's what to know about the unusually erratic and damaging weather.

Several states throughout the Midwest and South reported tornadoes overnight, with widespread damage and multiple fatalities reported in Missouri. KSDK's Megan Kernan and Travis Cummings report on the latest damage.

The dynamic storm from Friday through Sunday had earned an unusual “high risk” designation from weather forecasters.

Tornadoes whipped through Missouri on Friday night, ripping apart homes, businesses, and the electrical system. Gov. Mike Kehoe’s Office says at least 12 people have been killed and one person is still missing from the severe weather.

The weakening but still volatile weather system was moving Monday into the US Southeast and Mid-Atlantic, bringing thunderstorms, hail, damaging winds, and the potential for more tornadoes.

Tornadoes killed at least 33 people across several states in the U.S. Midwest and Southeast on Saturday night, CNN reported. Missouri reported 12 fatalities spanning five counties, the state's highway patrol posted on X.

The most fatalities were in Missouri. Forecasters warned that tornadoes, hail and violent winds continue to threaten states in the Deep South, from Louisiana to Georgia.
