At least 12 fatalities have been reported in Missouri, according to the Missouri State Emergency Management Agency. The deaths come as a massive storm system moving across the country unleashed winds that damaged buildings, whipped up deadly dust storms and fanned more than 100 wildfires.

The threat of tornadoes moved east into the Mississippi Valley and the south on Saturday, just a day after a massive storm in several central states.

Numerous significant tornadoes are expected Saturday afternoon and evening, with the highest risk across several states in the Deep South, forecasters say.

Storms, tornadoes, and car crashes killed at least 17 people states from Texas to the Deep South, and more severe weather is expected.

A severe weather system spawned intense, long-duration tornadoes that struck parts of Arkansas, Mississippi and Missouri, leaving some communities in tatters.

The fast-moving line of storms was capable of producing destructive winds over 70 miles per hour and potential tornadoes, and was expected to clear the Chicago area and Northwest

Tonight will be mostly cloudy and warm. Overnight lows will be in the mid to upper 50s, which is well above the average high for this time of year.
