I don't watch a lot of ANY TV news because I got sick of the near-constant BS. For weather I watch national radar/satellite and read what the National Weather service reports with some radio when driving.
Over-reporting is a real problem because if everything is a "MAJOR DISASTER OMG OMG OMG" then nothing happens, when there's realistic high disaster potential many people won't listen.
Its more of a problem with snow storms where they treat a 2-3 inch dusting with gusty winds like its a blizzard. They'll give any even slightly unusual weather event a trendy name and try to spin it into a headline.
