Deb, It's a fair bit warmer here. Not in all parts of Pa. Most southern parts of Pa are zone 6b, with some of the mountain areas out near Pittsburgh being 6B. The higher elevations and more northern parts, especially up around Lake Erie are zone 6a & in some areas zone 5b.
I'm in a suburb of Philadelphia which sits on one of the Atlantic Ocean bays, the Delaware Bay. We have a big maritime influence so we are the warmest spot in Pa.
