Hi patbiedermann and welcome to this forum .....
Glad to know that you are re-entering the work force after your surgery ..... it is a scary time, but you will make it!
I do not have the fuzzy head/off balance feeling that you do when a front is coming through, but I sure do have what I call barometric pressure headaches ..... totally unrelated to my AN though because I have had them for as long as I can remember. In fact, that is the only time I have headaches any more. A number of my friends can tell weather changes by the way their knees or hips feel. Therefore, I would have to imagine that some people can experience what you are from barometer changes.
One thing about it, the change is usually short-lived and if you know what it is, you can be extra careful in that situation. I guess I would reduce the amount of caffeine intake at those times because in some people that makes them more off balance.
Best thoughts.
