What's the weather like tomorrow in San Francisco?
It will be Sunny all day on Sunday in San Francisco, with temperatures of around 30 degrees celsius.
My aunt wants to visit but she doesn't like it when it's sunny. Find out when it will be cloudy. 
It will be Cloudy all day on Wednesday in San Francisco, with temperatures of around 14 degrees celsius.
Oh that's great, I'll be sure to tell her to see if she can visit then. I like the views when it's a little foggy as well. 
Is there anything else that I can do for you?
My brother's in Pittsburgh right now. How's the weather there tomorrow compared to San Francisco?

Well sounds pretty bad. Thanks for the help, that's all I needed to know. 
Thank you and goodbye.
