Hello!
Here is a lesson plan about the weather. I thought grade 1 middle school students needed something a little more challenging so I focused on weahter idioms. The attached files are a lesson plan, questions for a game, a powerpoint and a group idiom activity. The lesson starts by going through a powerpoint about the weather, then discussing the word idiom, studens divided into 6 groups and each given an idiom where they have to try and guess the meaning, and then a game to review what we have learned.
