Present and Future Possibility
May and might are used to talk about possible things that might happen. These possibilities can be about things that might be happening right now (present possibility) or things that might be happening in the future (future possibility).
Present Possibility
Kate: "Hey Sam! Have you seen Bob?"
Sam: "No, I haven't. He may be at work right now."
Kaitlyn: "Who's that?"
Greg: "I don't know! She might be our new manager..."
Future Possibility
Kate: "Look at the sky! There are so many clouds."
Sam: "Yeah. It's also cold. It might snow tonight."
Kaitlyn: "Where's Kate?"
Susan: "I don't know. She may come late."
Use may or might when something is possible but not certain. If you are certain about the present, use the simple present or the present continuous. If you are certain about the future, use will or be going to.
Possible but Not Certain
Greg: "Where's Emily?"
Kaden: "I don't know. She might be upstairs."
John: "We need to be in class by 9:00."
Bob: "The bus might not be on time. It's often late."
Certain
Sara: "Where's Robin?"
Conan: "She's in the kitchen. I just saw her."
Asa: "We need to be in the city by 8:00."
Koan: "The train will be on time. It's never late."
