I suppose it's a possibility for people to subconsciously detect an incoming thunderstorm, but I doubt anyone can do it at will. Besides, it's probably more coincidence than anything.
idk about coincidence, it happens almost every-time before it storms. I'm sure I can't do it on demand yet... but who knows...*rubs nipple* "There's a 50% chance that it's already raining"
You could just be subconsciously noticing signs of a thunderstorm, which makes you think there's one coming.
Although personally, I think it's just coincidence. You couldn't have possibly tested this that much, as you probably don't get that many thunderstorms in any given week.
this has been going on for years, but a coincidence sounds like a good possibility.
