potential change

Hope you can help.  The question is – “You are planning to take an impromptu guest out for a day of walking and want to consider a potential change in weather that could impact your plans. Beginning on a clear summer morning at a location in Ohio at 42°N latitude, how might temperature, atmospheric stability, and humidity change throughout the next 24 hours, and how could this impact your day of walking? Describe the initial changes relative to temperature, humidity, and stability and determine whether a day of walking would be a good idea or whether you should change your plans.”
