What is with this rainy weather?

I woke up this am with a major migraine headache. I haven't had one since Kordyn was about 2 years old. I finally got medicine to stay down and made it into school about 2 hours late and was only told 20 times that I was late. I think this crazy front is what triggered this. If it happens again, I will definitely go to the dr for medicine. Excedrin for migraines worked pretty well. I just had shaky hands all day?? Maybe from the caffeine? I feel for anyone who regularly suffers from these.
