Meteorologist Samantha Mohr, KPIX CBS5’s weeknight weather anchor for the past six years, has joined The Weather Channel in Atlanta. Mohr quit CBS5 in July after Roberta Gonzales was given the weeknight weather shift and Mohr was assigned to mornings. The Web site BroadcastNewsroom.com says she will be seen from 4-8 a.m. (Pacific) weekend mornings. Mohr, a multiple Emmy winner, is a native of Columbus, Ga., and was crowned Miss Georgia in 1985.
