A multifaceted storm that ravaged the Midwest on Wednesday night has spawned from multiple tornadoes in Missouri and Arkansas into heavy snow headed for Minnesota on Thursday. There is a chance that the storm might reach southeastern North Dakota, which is prone to floods. Missouri's governor issued a state of emergency and called the National Guard into action after the storm left thousands in his state without electricity.
