Storms are pushing into the southern Appalachians, bringing the potential for large hail and devastating tornadoes.

Severe storms hammered an area from Missouri into Illinois, Indiana, Tennessee, Kentucky and Alabama with dozens of tornadoes and hail to the size of baseballs.

Current situation:
The threat for damaging winds and tornadoes is diminishing across the Tennessee and Ohio Valleys, but the risk remains high farther to the southeast. Stay alert of the dangerous storm situation.

A Potentially Dangerous Situation Tornado Watch was issued for southeastern Missouri, southern and central Illinois, central and southern Indiana and western Kentucky before midday. The National Weather Service issues a PDS Tornado Watch less than a handful of times a year.

A line of nasty thunderstorms capable of spawning tornadoes is pushing from eastern Tennessee to central Alabama and Mississippi.

Southern Indiana has been hit very hard by large tornadoes. Major Chuck Adams of the Clark County Sheriff's Department says the town of Marysville, Ind. is "completely gone," according to local news.

"We are trying to gather info from across the state from ambulance crews and hospitals at this time. Reports of injuries are coming in and we are trying to confirm them," Dean Foener, spokesperson of the Tennessee Emergency Management Agency, said.

According to Hamilton County Emergency Operations Center in Tennessee, 6-10 patients have been transported to the hospital.

Many schools closed early across the Tennessee Valley due to the dangerous severe weather situation.
