Oh Noes.. CNN reporting a MASSIVE tornado 1/4 mile to 1/2 mile wide just SW of Wichita Kansas and headed NE directly toward the populated metropolitan area of Wichita proper.   Sirens are sounded throughout the area and a new TORNADO EMERGENCY has been declared. 
A Tornado Emergency is a more critical warning than a Tornado Watch.   A Tornado Emergency implies that loss of life and property are highly probable.
