Is Lightning Deflected to the West in the Western US due to Magnetic Fields?

[wakejosh]

in a magnetic field the force is toward the center of the circular path, does this mean lightning deflects to the West ? in the western US at least.

I found some stuff in my book saying that a proton released at the equator and dropped to Earth will deflect East. So it must be east. any feedback?
