Why are you learning to fly? If it's purely to get a PPL to use at weekends for your own pleasure, then learn in the UK. If you can't handle cancelling flights because of weather, you won't enjoy flying in the UK after you get your PPL anyway, so save yourself some money and don't bother.
On the other hand, if you're looking to move on to CPL or ATPL, and want everything done as quickly as possible so you can start looking for work, then go for it! And try the Wannabes forum, where you'll find some more sympathetic ears. But I don't think that's what you're trying to do, from reading your post.
Other people have also mentioned that training in the UK will better prepare you for UK weather, UK airspace, etc. As a Brit, who learnt to fly in England, and is currently in the USA flying, I know that the airspace regs are quite different in some areas.
Whatever you do, though, have fun!
