Peter wants to do simple monitoring of his local weather. Suppose that the main weather types are: sunny, cloudy, showers, rain and snow. He knows that the weather changes from one day to the next in certain patterns, depending on the season. He also has access to the local weather forecast for the following day, and he has been monitoring this for long enough to know that the local forecasters get it right about 70% of the time (though slightly worse for cloudy and showery days).

Build a DBN to model this problem. You should use a BN software package that specifically supports DBNs (see Appendix B).
