effective radio ads

I was driving back from work yesterday and decided to listen to some music instead of my usual podcast. I tuned to the classical music radio station. After a little while, the weather forecast came up. They started with the local forecast: -10 C (14 F) and snow. Then moved on international forecast: Paris - sunny 5 C, London - Overcast 9 C, Venice - Sunny 10 C, Miami - Sunny 20 C, etc. And then, as I am starting to think to myself that I am sick of the cold and that 10 C (50 F) would be pretty sweet, there comes the travel agency ad! I thought this was really clever and sneaky intro for an ad, that made me laugh!
