I've watched TWC for decades but I find their weekend, daytime segments and evening coverage to be lame.
I want weather. Not the fluff pieces about global warming or the 0light of wine growers. Weather nation has become a much more reliable source on a daily, 24 hour basis. While WM is reporting tornados in the evening, TWC is showing tow trucks and, well, more tow trucks.
WN has taken something that works and isn't "fixing" it. TWC has taken a working formula and broken it.
