Met men are normally more than happy to talk about weather, especially if you talk to the duty forecaster, rather than an observer. If they are not too busy, then they will normally tell you exactly what they expect to happen and why, in much more detail than a TAF/METAR.
If you ask qustions like, id like to fly from a to b, and return at time c, do you think the weather is going to hold out, you get a much more detailed answer than if you ask can you tell me the current metar for airfield a?
