A storm of controversy has engulfed The Weather Channel, after a 40-something former anchor accused network brass of washing her out of a high-ranking job to make way for a hot front of sexy young weatherwomen. Marny Stanier Midkiff, 42, this week filed a lawsuit claiming she was booted in the fall of 2003 as part of a reputed "reorganization" of the storm channel, which she believes was really an excuse to get more young female weathercasters on the air.
