The statement "I can wonder about the weather" is true because While in some places weather is the same from day to day, for many people it changes often.  Different types of weather can have profound effects on our plans.  For example, we might decide to postpone a picnic if heavy rain is forecast for the day on which the picnic was planned.  Expectations regarding the weather effect the way we dress to go out;  we need to be warned about potentially catastrophic weather events such as blizzards or tornadoes.
