Was the weather ever loyal to me?

1. I know that when newsreaders say the weather is "treacherous" they mean it's unstable/deceptive, but when I look out the window I can see how bad it is, it hasn't changed suddenly, so it's not unstable or deceptive. What the hell are they talking about then?

Is the weather actually going to be betray me?

2. David Tennant = Richard Hammond.
