Collins Improve your Grammar says that might cannot be used for future possibility. The books says:
Always remember that might is in the past tense form. May is correct when the outcome is still unknown.
The example sentence is:
He might leave for New York tonight. (wrong)
Collins Improve your Grammar states that the sentence is wrong and it should be He may leave for New York tonight.
I think with both may and might the outcome is unknown. Could you please shed some light on this?
Put that book in file 13 where it belongs.
- When indirect speech is introduced by a verb in the past tense, might can be used as the past tense of may: She said that she might go and stay with her mother.
- There is no future tense, but might is used for talking about future possibilities: It might rain tomorrow.
See entry A2
used to express the possibility that something will happen or be done, or that something is true although not very likely:
- I might come and visit you next year, if I can save enough money.
- Don't go any closer - it might be dangerous/it might not be safe.
- Driving so fast, he might have had a nasty accident (= it could have happened but it did not).
- The rain might have stopped by now.

No, no, no!
Keep that book out of the reach of children!
It might harm them (in the future).
Mr. TomHe might leave for New York tonight. (wrong)
OMG. I'm going to have a heart attack.
Mr. TomCould you please shed some light on this?
I am too shaken. I can't even speak. Maybe next week, when I've recovered from all these linguistic shocks.
