Not just cable news - every morning after the Ebola/Isis/political news, CBS always has a story on extreme weather somewhere. If not in the US, then elsewhere. However, "extreme" is not really extreme as drought, blizzards, hail, tornadoes, heavy rainfall, etc. have always been with us. With winter coming, they will no doubt ramp up the hyperbole.
Every cold front that comes through will be called the “Polar Vortex”.
