> B: The forecast says it's going to snow. **Haven't you checked?** (How could you organize a game without knowing the weather?)

2 & 4 could be either a simple question.

> A: Do you feel like going picnic tomorrow.

> B: It's going to snow. **Have you heard?**

Or in certain situation, it can be a challenge about whether the listener truly understand the consequences of snow weather.

> A: Should I water the lawn?
>
> B: It's going to snow tomorrow. **Do you understand what that means?** (As if A already knew the fact that it's going to snow.)

They mean similar. It depends how you use them and the tones you use.

Basically, 1 & 3 sound like you should know it. Well, 2 & 4 usually are generic questions for checking whether you know it.
