I wanted something with a bit more "flair" than the Mac Weather app in my menubar, and I found this gem:
https://urtti.com/weather
I really like the presentation of data - by no means the most comprehensive Mac weather app, but I have more detailed apps on my phone if I want to drill in to the weather, and I don't need all the detail that iStat Menus Weather thing presents (as well as all the background processes that iStat Menu adds - nothing against iStat Menus, I just decided not to install it on my new Mac.)
