Cur-sed vs Cursed? [View all]

"cursed" - does it have different meaning if it's pronounced ˈkər-səd vs ˈkərst ?

I woke up to rain and decent temperatures after a hellish summer and the phrase "cursed summer air" came to mind. In my head it was clearly cur-sed implying that the air itself is the curse, the morning breath of Sauron himself. In contrast the short pronunciation implies to me that the air is the victim of a curse.

Is this just me?
