I think its a shame some of them are recorded as its nice to see a bit of interaction between the weather presenter and the newsreader.
Yes I also agree with what you're saying. Sometime it can be quite funny. For example, months ago, Carol Kirkwood placed her hand on Peter Dobbie's knee, and told her to get her hand off! As a result she laughed and laughed all the way through her weather broadcast. It was very good indeed!
