The season premiere, titled 'The New Hotness' will see Station 126 "called into action to a county fair when a 'derecho,' a series of fast-moving groups of severe thunderstorms, hit Austin, causing hurricanic and tornadic-force winds, heavy rains, flash floods and a wide path of destruction," according to Fox's logline.

"And just when they think it couldn't get worse, an even more rare weather phenomenon, a 'heat burst,' causing temperatures to go up to 122 degrees Fahrenheit, hits the city."
