I live in Calgary, Alberta, and we get "Chinooks" that blow in A LOT. It's when a warm wind blows over the mountains and pushes the cold air out. The barometer drops dramatically in a very short period of time. The temperature can go from freezing cold to warm in a matter of minutes!!
So yes, I get incredible "chinook headaches" as they're called. I can predict the weather change up to two days in advance! My friends and family call me a walking weather station! Nothing gets rid of the pain except sleep and time.
I was diagnosed 3 weeks ago with simple partial seizures due to my Lupus. As soon as I started taking anti-seizure medication the headaches stopped! We've had 3 Chinooks in those three weeks, and I haven't had a single migraine! Weird eh!! I have told my Neurologist and he is very curious about this!!
So no, you're not alone. Calgary understands!!
