"It is raining soon/tomorrow"; what's wrong with it?

I think they're both okay.
According to the plan/prediction, he's leaving tomorrow afternoon/ it's raining tomorrow afternoon.

Similarly, he leaves / it rains.

Hi,

"it's raining tomorrow." is grammatically correct but I'd rather say, "It might be raining tomorrow" instead. Since I'm not sure if it will rain tomorrow. But maybe it depends. I'm not sure if it's natural for native speakers to say "It's raining tomorrow".

AnonymousThe sentence "it is raining soon" or "it is raining tomorrow" seems incorrect, but at the same time"John is leaving soon / tomorrow" seems perfectly okay. What's wrong with the "rain" sentence?

John is capable of arranging to leave, capable of scheduling his own departure.

The rain does not arrange to happen.
Rain is an inanimate phenome

My thought was, "According to the weather report, it's raining tomorrow afternoon."

Why don't we schedule the game for tomorrow afternoon? (reply) It's raining tomorrow afternoon.

I'm the original poster. Let me add some context:

------------------
Tina: It is raining soon.
Mary: ___ it rains, go into the building.
------------------

This pair of sentences appeared in a test for ESL students; I contend that Tina's utterance is problematic and thus the question should be revised. Should this question be revised?

I agree. I know I wouldn't say it. I'd say

It looks like it's going to rain soon.

Or maybe without soon. That seems unnecessary.

CJ, this "raining" issue reminds me of your fine article on wishing.
I hope it's raining tomorrow afternoon.

Well, I don’t think “it is raining soon/tomorrow” are wrong. They sound just fine to me and appear in the weather forecast. People don’t ALWAYS talk grammatically or correctly, or perfectly in conversations. Just like what Avangi said, “it is raining soon” is from a speaker, I, so “I hope” can be omitted in the original sentence. Thus, that should be a when issue in the answer.

I don't think Tina's remark sounds anything like a weather forecast. It's a remark in the context of a conversation about staying outside or going into a building depending on the state of the weather.
