M: Well, you didn't expect it to be warm, did you?
W: Of course not, but I heard the national weather service's prediction for the next 90 days.They said it's supposed to be much colder weather than usual.
M: Yeah, maybe.Personally, I think those long-range forecasts are useless.
W: Not as useless as you think.
M: Oh, come on, when you're talking about what's going to happen three months later, you might as well just pick a forecast out of our hat.
W: Well, you're partly right.They aren't very good at the amount of water falling on the earth.But they are much better for temperatures especially for this time of the year.
M: Really?So I should take them seriously about the cold but not count too much on a lot of extra now?
W: Exactly.
M: But what did you say about this time of the year?Do some seasons really give them more problems in making forecasts?
W: Autumn is the worst; apparently weather patterns change so much then.Just think how variable our weather has been the last three months.
M: That's true.It probably would have been hard to predict all those changes back in the summer.You know, you're beginning to convince me there is more to forecasting than I thought.How come you know so much about it?
W: I get my information from an expert -- my sister.
