22 Chapter 2 Asking Siri for Information Weather Siri keeps on top of the weather forecast for you. When you ask, "Will it rain tonight?" (Figure 2-1) or "What is the temperature?" Siri offers immediate feedback. Asking "What's the weather for this week?" provides the full weekly forecast. As a rule, Siri replies with simple answers. If extensive charts are involved, you are prompted to look at the phone rather than just listening.
