What are these two people talking about?

M: What kind of dress are you looking for?
W: Since it’s getting warmer this time of the year, I want something lightweight. What do you think would be the best?

W: Good morning, can I help you?
M: Yes, I’d like to know something about the weather in Arizona in the coming week.
W: Well, it will be fairly hot and there will be much rain.
M: I see. Thanks very much for your help.
