Howdy all,

I've been noticing some fret buzz on my A string when fingering the 11th fret. Would that be a simple bridge adjustment? I'm not getting any noticeable buzz anywhere else, but I can hear this through the amp. Thanks!
you are just having a high fret. bring it to you local dealer he will repair it for you
Could be the string's height, the relief, or, as someone already said, a high fret. Sometimes all you have to do is replace the string.

The changing of the seasons right now can change your neck's relief. I'd check that out first probably.
