Hi @Snehashree21,

Thanks for the contribution — I tested the preview and the 3-day forecast feature is working well and integrates nicely with the existing UI.

However, there is still a merge conflict in script.js, so I’m not able to merge this PR yet.

Please pull the latest changes from the main branch and resolve the conflict. Once it’s conflict-free and everything continues to work correctly, I’ll proceed with the merge.

Thanks!
