I recently brought my Meyer Lemon inside because we have been having unseasonably cold weather in Atlanta. Yesterday, I noticed 1 or 2 leaves that have started yellowing a bit. Here is a pic that shows the yellowing leaf:



It seems odd that it is just happening to 1 or 2 leaves (the rest look fine) so I'm wondering if this is just normal for older leaves that may soon drop or might it be something else?

The way that the leaf is turning yellow certainly looks like an old leaf dropping from the tree. This type of leaf is quite common this time of the year. - Millet

Thanks for the quick reply Millet. I was hoping that was it but was a little concerned since I noticed it not long after bringing the plant inside. I've gotten some nice growth towards the end of summer and it is in full flower now (thanks to the great advice from you as well as countless others here) and I hope to keep it healthy during the winter and have a really great year next year.
