I really like Breezy Weather. You can remove elements you don’t want and it seems to support rain notifications.

I’d use one of the atomic versions, as these are the most similar.

Then there’s Silverblue with Gnome which has a minimal modern interface, and Kionite with Plasma with a customizable more classical desktop. Might be best to match that with her setup too.

You’re not tired, but you saw a post about yawning? Well, guess what.

Clock but it’s made by an LLM:
