Pumpkins and Mums, But Where is Fall?

I'm starting to get ready to pack up for Florida for the winter. 

We will be leaving in 3 weeks, so I'm really hoping to enjoy some fall weather here in Pennsylvania before we leave. 

I bought 3 pots of colorful mums today for our front porch and one for under our tree. The rust colors and bright yellow and golds feel like fall.
