  That's such a drag!

talking about weather

For rain, snow, wind, fog, or hail, you can use "有……" (yǒu), but if it is sunny/clear skies, then use "是晴天" (shì qíng tiān).

2. 怎么样

"怎么样" (zěn me yàng) in this case means "...(some topic)..., what's it like?" or "How is it?"

3. 出去

" 出去" (chū qu) is a special construction. "出" (chū) is the verb, and "去" (qù) here is acting as a directional complement. There are two directional complements, one is "去" and the other is "来." (lái) These directional complements indicate in what direction the action is taking place in reference to the speaker, for example: "出去" means "go out" and "出来" (chū lái) means "come out." Directional complements are only used after certain verbs. Some of these are "出", "回" (huí), and "拿" (ná).
