W: We'd better be looking for sales on jackets and underwear. It's going to be really cold this winter.
M: Well, you didn't expect it to be warm, did you?
W: Of course not, but I just heard the national weather services 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 are talking about what's going to happen three months later, you can not count on the long- range weather forecasting.
W: Well, you are half way right. They aren't very good for rainfall. But they are a lot 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 snow?
W: Ahha.
M: But what did you say about this time of the year? Do some seasons really give them more problems in making forecast.
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 hack in the summer, you know, you are beginning to convince me of the value of weather forecasting. How come you know so much about it?
W: I get my information from an expert. My sister works at weather bureau.
