>> we have one of our stronger upper air disturbances from the spring that's come in from the pacific northwest , pushed its way southeast and now it is gathering up some of that gulf of mexico moisture. we have winds from the southeast that are moist and warm, winds aloft from the southwest. so the turning of those winds allows the storms to develop rotation. we call them super cell thunderstorms and those are the ones that produce lots of dangerous tornadoes .
