Why is the snow so flat? :(

I'm just worried that the weather won't be gradual like in sims 3. Sims 3 did a wonderful job with the various effects, like glass windows frosting and fogging over in the cold etc. And rain would slowly pick up, not start out as a thunderstorm right away. Snowfall also started out light.

Edit: Saw a screenshot and there IS frosted glass at least! yay! Loved that touch in sims 3.
