Hello
Being an expert here yourself, you must know how hard it is to make a solid diagnosis over the internet. In fact, it's unethical to do so without the benefit of a physical examination and lab tests.
Your scar could have some hypertrophy. Hypertrophy of a scar is an over growth of tissue due to increased size of the cells. This can happen most often when a scar is near or on a joint such as the shoulder. Signs of hypertrophy are increased inflammation and pain.

With arthritis, once the weather is constant again, and the body adapts to the barometer, the pain can subside until which time the barometer, or weather changes again.
In order to find out if you have arthritis, you would need to have diagnostic studies done, including blood tests to look for arthritic markers. I wouldn't be able to tell you unless the tests were done, and then it would be the doctors decision, or diagnosis if you will.
Please let me know if you have more questions.
