We often ask Bob behind the scenes to tell us more about why things are happening in the skies. Or what are the cloud formations and even what are hurricane force winds? Bob French always has the answers.

So we wanted to share this knowledge with you in our new segment called Bob's Weather Why's? This segment will feature every Monday right after Bob's weather forecast for the day.

Today's question: Why is the Harvest Moon orange and big sometimes?

If you have Weather Why's for Bob send them to news@kagstv.com.
