Severe storms leave path of destruction across several states; more in store.
Storms cut a wide path of destruction across the country over the weekend, and forecasters are warning that may just be the beginning.
A tornado slammed into Mapleton, Iowa Saturday evening without warning, leaving blocks and blocks of the small town shattered.
A different system brought drenching downpours, baseball sized hail and a sunday full of cleaning up to parts of the Carolinas and southwestern Virginia.
The violent storms follow days of unusual heat in some places, with the warm dry air in Texas fanning wildfires.
Other areas saw unusual cold.
A foot of snow fell in Arizona.
"This time of year we often see these huge temperature swings driven by a jet stream that is moving from the winter mode into the summer mode...and the battle between the warm and the cold is what's helping to fuel these severe storms," explains the Weather Channel's Maria LaRosa.
Forecasters warn the danger is not over yet.
A strong storm front is expected to move across the mid-section of the country over the next couple of days, bringing the potential for dangerous weather to about 40 million people across 20 states.
