What does this mean?

Ok, so i have decided that the weather service is run by very twisted folks. Most of the time. This dawned on me last night during the news. There were frost warnings north of here and a frost advisory here. Why not a frost watch? I got thinking about that... Folks wouldn't do it. Ok, except my grandfather. He would have been out there with a shotgun keeping his eyes focused on his veggies and saying threatening things to keep the frost away. But, he's dead, so i guess he gets to watch frost from a whole other prospective now.
Those guys must know the implications of watches. They have to have heard of a bird watch. It's a tornado watch. Ok. Outside we go. Watch, watch, watch, far from tv and radio in the middle of a field. We discuss probabilities and throw up dirt to see if it does something weird that must mean one is coming. We watch the color of the clouds. But, we watch. Now, if the tornado shows up, they suddenly decide to change the watch to a warning and yell for everyone to run and hide. But, we're still outside watching. Same for thunderstorms, winter storms,...
I think that they are part of the news industry on purpose. They lure out unsuspecting literal folks who do exactly what someone tells them. (cut to me at 10. Mom: "Take the potatoes out of the oven." Me: "Ok." Mom after dinner: "Who left the oven on?" Me: "You didn't tell me to turn it off!") These people are the ones that all the reporters get to interview later. See how that works? The team needs people to interview about how terrible it was and what it looked like. They need victims who had to take shelter in ditches and dig foxholes in fields. They get the scoop because the meteorologists set it up. The reporters may already have people in mind before the weather event even happens.
Victims of frost just don't get the public's sympathy. "He just sat there all night next to the squash until his toes froze off?" It's just not something the public thinks of as compelling news. That's why it's an advisory and not a watch.
