Snow in September?

As far as I know, it is still summer and that fall will officially make its entrance by September 23.
So how come na mag-snow na daw bukas???

Now I am worried. What if winter will really come early? I love winter -- but not in my pregnant condition. I still have a lot of doctor and clinic visits to do ALONE. It's also quite difficult to put on winter socks and boots with a bulging tummy.

Oh weather, please be cooperative!
