The move away from scientific forecasting of the weather to sensationalized leftist political advocacy is in part due to the influence of Wonya Lucas, executive vice president and general manager of The Weather Channel Networks.
Lucas admitted in a recent interview with Media Village that the reprogramming of The Weather Channel was influenced by her tenure at CNN when that network shifted from presenting straight news to personality-driven programming.
Lucas decided that what was good for CNN was good for The Weather Channel, and the objectivity and respectability of the network has now been thrown out the window. It doesn't matter that CNN's turn to the left has caused their ratings to plummet; The Weather Channel's embraced its model.
Media Village reported that the move by The Weather Channel "is intended to establish a broader perspective on the weather category and, says Lucas, to move the brand from functional to emotional." [emphasis mine]
