Text google (466453) for weather

Basically text the number and type Weather ZipCode, (example Weather 90210 or Weather Beverly Hills, CA)
City and state works too.

I've been using google for years, weather, for directions, nearest resturants, many things. Its actually really useful. You can even ask it random questions like what color is the sky?, when was the united states founded?, etc etc. No joke.
