Thats an interesting question a buddy and I have been testing that type of theory off and on for about a year + we were last focused on the barometer just prior to rain (we even stayed and fished in the rain lol).... but not so much on frontal movements but we noticed fronts do affect the barometer but not as much as rain.
What we did find is the Barometer we bought (at BPS) would shift usually with-in the course of about half an hour some days 2 or three times but when the Barometer went from HIGH TO LOW is when we did best fishing.
(Not trying to mis-direct your thread)
It seem to fall along the same lines maybe you can use it somehow
